Full textAbstract:
The slope is a surface that lies at an angle to the horizontal. If the driving force at the slope is bigger than the resisting force, it can inflict a landslide. Gabions are one of the slope reinforcements structures that can be used to prevent landslides. Gabion has woven wire and has tensile strength. This study aims to examine the effect of modeling of tensile strength on gabion wire using Plaxis 3D, as well as the effectiveness of variations in height, variations in tensile strength, variations in gabion reinforcement patterns on slopes. The soil is modeled as homogeneous loamy sand with a geometry of 10m high and 1:1 slope. Modeling the tensile strength of gabions can increase the value of the safety factor by 9.5% compared to without modeling the tensile strength of gabions. The optimal gabion height that increasing the safety factor is 6m. The value of the tensile strength of gabion wire does not have a significant effect on the safety factor of the slope. The placement of gabions with a zigzag and lined pattern and a gentle slope will more increase the safety factor.

Full textAbstract:
Gabion has been extensively used in retaining walls and slope protection. This study carries out a safety risk analysis of a new structure combining basalt fiber reinforcement (BFR) and the traditional gabion structure. The micro-parameters of BFR and soil were calibrated by using the 3D discrete element method after the tensile test of BFR was completed. The mechanical property of the gabion unit was investigated by using a refined model and a numerical test of uniaxial compression. This work developed a simplified method to simulate the seepage effect. The stress condition and sliding displacement between gabions were also investigated. Deformation, stress, and porosity were all used to evaluate the stability of the new type of gabion slope. According to this study, BFR has a tensile strength of 68.22 MPa, and the safety factor increased by 25.68% after using these BFR gabions. The damage is mainly manifested by bending the BFRs and the dislocation of the gabion units, as the slope does not slip. It is indicated this novel gabion structure has a lower safety risk compared to traditional ones, and thus can be popularized and used in retaining walls and slope protection.

Tandem V-shaped gabion weirs for improving spawning habitat for salmon (Oncorhynchus spp.) were installed to replace large organic debris at three sites below the terminus of a debris torrent in Sachs Creek, Queen Charlotte Islands. Stream conditions were compared between gabion and nearby control sites. The stability of added and entrapped gravel at all gabion sites was poor over the first winter and excessive scour threatened the integrity of the upstream steeper (3%) slope gabion site. However, the two gabion sites at a lower (1%) slope successfully stabilized spawning gravel in the 2nd year after installation, probably through a reduction in the local slope gradient and self-armouring of the high flow channels. Higher summer densities of juvenile coho salmon (Oncorhynchuskisutch (Walbaum)) and steelhead trout (Salmogairdneri Richardson) were recorded at the gabion sites (means, 1.2 and 0.33/m2, respectively) compared with the control sites (means, 0.89 and 0.10/m2). Underyearling coho fry were also significantly larger (p < 0.05) at gabion sites (mean, 50 mm) than at control sites (mean, 45 mm). Improved rearing habitat was created for coho juveniles by the gabions, a result of increased pool area and cover.

Retaining walls have been classified and characterized as structures protecting road or railway embankments against landslides. Particular attention was focused on retaining structures classified as light [1-3, 5-12, 14-24], which include, among others, walls made of gabions. Physical models of the gabion retaining wall, prepared on a laboratory scale, test stand and how to perform spatial deformation tests are presented. The models differed in the number and dimensions of gabions. On the basis of measured horizontal deformations of embankment models with a gabion wall, which were subjected to vertical static pressure at the level of the embankment ceiling, the values of basic strength parameters were determined. In particular, the value calculated: horizontal pressure coefficient, shear strength and modulus of deformation. The variability of the values of these parameters was estimated as a function of variable factors related to the gabion wall configuration (determined by the number and dimensions of gabions) and the value of the external load test.

Full textAbstract:
Gabion structures are widely used for force protection as they enable locally available material to be used, reducing logistical expense. The soil fill within these structures provides the blast and ballistic resistance; hence, any localised variation in the contained soil can potentially lead to reductions in protective capability. Specifically, built gabion structures were monitored in internal and external environments to assess the variation of soil moisture content and density over a full year and with changing weather conditions. The gabions were filled with fine sand according to manufacturer’s instructions. Internal and external moisture content readings were recorded at regular intervals, and a continuously monitoring weather station was installed to collect comparative data. LIDAR scanning was used to record the shape and volume of the gabions to estimate variations in the density of the soil fill. The data indicate that moisture content can vary by over 20% between the top and base of the gabion, and by over 5% from face to face and between readings depending on recent weather conditions, while the core of the gabions remains relatively unaffected. This leads to localised variations in density which can impact on both the ballistic performance and blast resistance of the structure.

Full textAbstract:
The stability of roadbed in seismic prone areas is vital for the sustainable economic development of regions. The gabion structures are one of the methods of road strengthening. Gabion structures are used to avoid damage to the roadbed under loads of natural ground slope due to earthquake or other reasons. This approach is one of the most economical and efficient solutions for the stabilization of natural ground slopes, and it is efficient as a drainage system. Field tests give precise results about the efficiency of gabion types for different sites. However, in some cases, it is expensive and numerical calculation can be used for the estimation of the applicability of gabions. The stability of roadbed by using finite element approaches was investigated here. Stability was considered as results of calculations by two cases with gabions and without ones were compared. The dynamic and seismic impact was taken into account according to local normative documents.

"Use of construction and demolition solid wastes for basket gabion filling."

Full textAbstract:
Construction and demolition wastes have been studied by technical means aiming at the development of management tools to reduce their environmental impacts. Among these, recycling can be highlighted. This paper aims at the technical assessment of basket gabions filled with construction and demolition solid waste. Gabions are usually used for retaining walls construction, and these are commonly filled with rocks. Retaining walls are essential for earthfill slopes stabilization, and they must have proper characteristics of strength. However, depending on the slope height or the technical responsibility of the retaining wall, alternative materials with proper characteristics could be used to fill the gabions. The use of recycled material for gabion filling could reduce environmental impacts and costs caused by retaining wall construction. So, basket gabion cells were filled with construction solid waste and basaltic rocks, both crushed into coarse granulometry aiming to compare technical characteristics among them. The performed laboratory tests showed that the horizontal and vertical displacements determined for gabion filled with wastes were near to those obtained for gabions filled with basaltic rocks for a retaining wall of 5 m and up. In conclusion, it can be drawn that basket gabions filled with construction and demolition waste may be a technical alternative for civil construction, reducing environmental impacts and raw material consumption for retaining wall execution.

Problems related to the design, construction and operation of typical retaining structures, presented in the form of monolithic and precast and reinforced concrete, are studied under the climatic conditions of the Irkutsk region. A comparative analysis with gabion basket structures is provided and the advantages of us-ing gabions are revealed. The costs of materials that make up the cost of gabion structures under real con-struction conditions were studied in detail and constructive technological solutions were proposed for the construction of these supporting structures. The natural stone laying technology in partial volume of con-tainers, i.e. its use on the face, visually visible surfaces of mounted boxes, was chosen as a reserve for reducing the cost of gabion structures. It is established that the main visually unseen volume of gabions can be filled with other materials: crushed stone of various fractions, gravel, cobblestones, concrete scrap. Moreover, the use of the specified aggregate containing small fractions requires an additional measure that does not represent a significant increase in material and labour costs – laying in the process of filling the boxes of the vertical dividing wall of geotextiles along the boundary between “face stone" and “other filling”. According to the preliminary technical and economic study of the proposed options of filling gabions, the possibility of a cumulative reduction in the estimated cost of the construction of gabion structures amount-ed to about 20% of basic design, i.e. prices in 2019 could result in savings of 1500 rubles per 1 m3 of fin-ished products including all expenses – earthworks, transportation costs and landscaping – carried out at the end of the primary cycle of the work.

Full textAbstract:
The slope of the GI Kariangau, Balikpapan, East Kalimantan uses a combination of gabion and geotextile construction to handle landslides on the slopes. However, there was a failure that indicated deformation of the gabion reinforcement and damage to the geotextile sheet. The failure of the reinforcement was caused by a landslide on the slope. This design begins with the collection of the necessary secondary data. Then proceed to calculate the stability of the gabion reinforcement at each level. This was followed by modeling the slope using the Geo5 2020 slope stability demo version program to get the safety factor value. Analysis of the program was carried out under various conditions, namely slopes before and after reinforcement, excavation at the foot of the slopes, and variations in groundwater level. From the results of the analysis, the value of the slope safety factor before and after being reinforced was 5.46 and 5.76. An increase in the value of the safety factor before and after the reinforcement of gabions shows that gabions play a role in increasing slope stability. The value of the slope safety factor before and after the landslide was 5.46 and 0.78. The decrease in the value of the slope safety factor before and after excavation activities shows that excavation has an effect on reducing the value of slope stability but is still within safe limits. Rain conditions affect reducing the value of soil parameters so that it affects the strength of the slopes. The failure of the combined construction of gabion reinforcement and geotextiles was caused by a decrease in the value of the shear strength of the soil due to saturated soil conditions in the gabion reinforcement area.

The earthquake (Mw 7.3) that struck Nepal on April 25, 2015 caused damage to many civil engineering and architectural structures. While several road gabion retaining walls in mountainous regions incurred damage, there was very little information that could be used to draw up earthquake countermeasures in Nepal, because there have been few construction cases or case studies of gabion structures, nor have there been experimental or analytical studies on their earthquake resistance. Therefore, we conducted a shake table test using a full-scale gabion retaining wall to evaluate earthquake resistance. From the experiments, it was found that although gabion retaining walls display a flexible structure and deform easily due to the soil pressure of the backfill, they are resilient structures that tend to resist collapse. Yet, because retaining walls are assumed to be rigid bodies in the conventional stability computations used to design them, the characteristics of gabions as flexible structures are not taken advantage of. In this study, we propose an approach to designing gabion retaining walls by comparing the active collapse surface estimated by the trial wedge method, and the experiment results obtained from a full-scale model of a vertically-stacked wall, which is a structure employed in Nepal that is vulnerable to earthquake damage. When the base of the estimated slip line was raised for the trial wedge method, its height was found to be in rough agreement with the depth at which the gabion retaining wall deformed drastically in the experiment. Thus, we were able to demonstrate the development of a method for evaluating the seismic stability of gabion retaining walls that takes into consideration their flexibility by adjusting the base of the trial soil wedge.

The article deals with the design and scheme of gabions destruction in coastal areas under the action of frontal sea waves in the city of Sochi and on the Curonian Spit. The durability of gabions varies depending on the mesh materials, and the place of application. In case of gabion coastal retaining walls, the construction is made of metal and anticorrosive coated wire with an additional polymer coating, their durability is claimed to be several dozens of years but observations show that the structure may be destroyed much earlier. The actual scheme of destruction of these structures differs from those given in the regulatory documents. In spite of their possible destruction gabions prevent the development of landslide and suffusion processes along the coastline during their short lifetime. The article deals with the problems of gabion retaining walls failure under the influence of frontal sea waves which are not stipulated in the normative documents.

Full textAbstract:
Gabion structures are used in a variety of ways in Japan and around the world because they allow for the creation of simple structures at highly reasonable construction costs and completion periods. Previous earthquake damage surveys have shown that, in many cases, gabion structures did not collapse even though deformation was allowed, and have demonstrated that the wire mesh used in their construction has a high confinement effect on the stones filling the gabion. Despite this, gabions have not been actively utilized, nor have they been used to construct permanent structures in Japan because the design and construction of such structures are based on experience, and a standardized design method has not been developed. Hence, in order to facilitate development a design method for gabion-based structures, we must first go back to the basics and establish a detailed explanation of the wire mesh deformation mechanism of such structures. In this study, we performed tensile tests on wire meshes of different shapes in order to determine their strength and deformation characteristics and then conducted numerical analyses using the results obtained. The tensile tests revealed that deformation characteristics differed depending on the mesh shape and tensile direction. We also showed that the direction in which the tension acts and the mesh nodes are important, and that the test results could be reproduced via numerical analysis with the finite element method by using beam elements.

The retaining wall can be said to be safe if the retaining wall has taken into account its safety, both against shifting, the danger of overturning, and the carrying capacity of the soil. Gabions are zinc-coated or galvanized woven steel cables. This steel wire mesh forms a box or beam. The inside is filled with large stones of which size should not allow rocks to pass through the woven holes. The functions of gabions include protecting and strengthening the soil structure around cliffs, river banks, and embankments to prevent erosion or landslides, the way the gabion is installed and maintained itself can alsoaffect its strength.The purpose of this study was to determine the dimensions of gabion type slope countermeasures that meet the safety factor requirements, and to know the Budget Plan for implementing gabion slope countermeasures on the construction work Jl.

The variation between flow depth generated in front of gabion barrier and flow rate has been studied in open laboratory flume. Flow profiles have been observed for each of "Transition Flow" and "Overflow" regimes. Effects of gabion height and material coarseness on the upstream flow depth are studied by testing four different gabion heights and four different medium aggregate sizes. The analysis of experimental results showed that the relative decrease in flow depth varies between 38% and 17% for "Through Flow" type when material coarseness and discharge increase. In "Transition Flow" regime, increasing material coarseness and discharge causes an average decreases in relative flow depth of 7.6% and 4.4% for gabion heights 15cm and 30cm, respectively. Gabion begins to operate as an overflow weir when the average water depth to the gabion height (H/P) is 1.19. While the overall average increase in discharge relative to solid weir is 15%. Prediction relationships for flow depth upstream the gabion for each of the three flow regimes is suggested. Also, dimensionless relation to predict discharge coefficient are proposed with good accuracy.

Full textAbstract:
A gabion is one of the most commonly used cushioning layers to shield protection structures against boulders entrained in debris flow. Despite the prevalence of gabions, their cushioning performance is highly variable because of the wide range of rock sizes and cushioning thicknesses that are recommended in the literature. Correspondingly, the dynamic response of gabion cushioning layers varies dramatically. In this study, large-scale pendulum impact tests were used to calibrate a discrete element model. Subsequently, a parametric study was carried out to discern the effects of particle size and cushioning thickness on the impact load and transmitted load exerted by a boulder. Results reveal that as the particle size in the cushioning layer decreases, the force chains collapse more easily, and the expansion angle of strain energy increases. To optimize the performance of a gabion cushioning layer, practitioners should reduce the size of the particles to a normalized particle radius of about 0.1. A normalized particle radius less than 0.2 ensures that the expansion angle of strain energy is large enough — greater than 45° in this study — so as to enable load spreading across the barrier. To eliminate the effects of energy reflecting off the barrier and directed back to the point of impact, which augments the impact load, the cushioning layer thickness should be greater than three times the radius of the boulder.

Full textAbstract:
Applying rock-filled gabion to buildings in cold regions with mountainous climates has multiple potentials, such as utilizing rock resources, improving building sustainability and saving building energy. Therefore, it is necessary to analyze the thermal performance of gabion buildings. Based on the CFD method, this paper establishes a numerical model of buildings with gabion enclosure structures, analyzes the influence of the gabion structure on the external convective heat transfer coefficient (CHTC), wind pressure, air infiltration, room temperature and building load, and further uses the building energy consumption simulation method to analyze the heat load of gabion buildings. The results showed that the adverse impact of climate on the building thermal performance is significantly diminished by the gabion. Under different weather conditions, the CHTC, the maximum wind pressure difference on the exterior surface, and the air infiltration rate are reduced by different rates. Further, the room base temperature increases throughout the heating season, and the maximum heat load and the cumulative heat load of the building are, respectively, reduced by 10.6% and 24.8%. This work revealed that the gabion is an eco-friendly and adaptive measure to improve thermal performance and indoor thermal comfort.

Full textAbstract:
Scour is caused by the erosive action of flowing water, which causes materials from the bed and the banks of a river to be moved or unsettled. Hydraulic structures can be drastically impacted as a result of scour, which is why it is one of the most common causes of bridge failure around the world. With a predicted increase in climate conditions, the subsequent failure of hydraulic structures due to scour is likely to proliferate as the flooding of waterways is projected to rise. This study aims to determine the viability of introducing alternative materials to a scour countermeasure used in construction—gabion models—in a bid to improve the sustainability of a project whilst providing suitable scour mitigation measures. Existing literature was examined to comprehend the different scour countermeasures used, as well as the use of alternative materials that can be used as a scour countermeasure. A laboratory experiment was then carried out using a bridge pier embedded in a flume channel protected by gabion mattresses filled with alternative materials—stone, clothing and plastic—to analyse their effectiveness. The results demonstrate that stone filled gabions are most effective at reducing bridge pier scour. However, recycled clothing as a gabion fill could prove to be a viable alternative in construction projects, potentially leading to reduced construction costs and greater sustainability.

In order to study dynamic deformation behavior of green reinforced gabion retaining wall, lab test was carried out and the dynamic loads of 4 frequencies and 4 amplitudes were imposed. The total cycles of dynamic load reached 2 million. Lateral and vertical deformation behaviors of green reinforced gabion retaining wall were investigated, and the main factors which influenced the dynamic deformation behavior and their significance were obtained. Meanwhile, fatigue life analysis on green reinforced gabion retaining wall was made. The results show that dynamic deformation is greatly affected by amplitude and the cycles of dynamic load, not significantly affected by frequency. The maximum lateral and vertical deformation occur in the fifth layer of green reinforced gabion wall. With the increase of train load and train speed, fatigue damage and fatigue life of green reinforced gabion retaining wall can be estimated based on accumulative fatigue damage theory.

One of the most important issues in the construction of highways, mountain and urban roads is known as slope stabilization. If the necessary actions for protection are not considered, it could lead to problems and events such as landslides, settlements and even destruction of roads. There are many methods for stabilizing slopes such as Gabion walls and Tiebacks. This study can be used as the beginning of a new synthetic method where the Gabion wall is combined with Tiebacks. Gabion walls and tiebacks can be known as the most flexible methods of slope stabilization methods, because of this reason, if they can be combined with each other, it should show very good results in front of dynamic and even static forces. This combination is the novel point of this research. In this study at first, the gabion wall will be analysed in different loading conditions, and then to deal with earthquake dynamic forces the tiebacks will be used to increase the gabion walls stability.The software that is used in this study is GEO5 software, nowadays this software can be introduced as one of the best slope stability analysis software's. The results of this study showed that the designed gabion wall could be stable in dense silty gravel soil (GM) in 8.5-meter slope, and with magnitude of 0.25 horizontal coefficient of Manjil earthquake, but in the same geometry and material condition and impact of 0.4 magnitude horizontal coefficient of Bam earthquake it couldn't be stable alone. In this condition four rows of 18 meter tiebacks could stable the gabion wall very well. In this model, under loading condition 3 (with horizontal and vertical pseudo-static coefficient of Bam earthquake) that had the most vertical pseudo-static coefficient, the 23-meter tieback anchors with 12-degree inclination respect to horizontal could stable the considered gabion wall. This result could show that, the combination of gabion walls with tieback anchors gives a satisfactory result and it is an efficient and helpful method for stability of slopes in front of earthquake and dynamic forces.

Red-sandstone granular soil reinforced with gabion-mesh is a new concept of composite reinforced soil. In order to reveal the mechanical properties of this composite reinforced soil, a series of laboratory triaxial compression tests on specimens reinforced with gabion-mesh were carried out, and 3D discrete element method was introduced to simulate the triaxial tests. The macro stress-strain relation of red-sandstone specimens reinforced with gabion-mesh was reproduced by the 3D discrete element model. The results show that 3D discrete element method is an ideal technique to study the meso-mechanical nature characteristics of gabion-mesh reinforced red-sandstone granular soil.

Pada umumnya, pembangunan timbunan dapat dilakukan dengan beberapa cara, dan salah satu cara yang paling ekonomis untuk dilakukan adalah penggunaan perkuatan geogrids dan gabion. Akan tetapi, dengan target elevasi mencapai 37 meter, penggunaan perkuatan dengan jenis ini menjadi suatu hal yang sangat jarang dilakukan pada konstruksi geoteknik. Timbunan pada umumnya hanya mencapai 8-20 meter saja. Tantangan yang dihadapi adalah bagaimana menentukan konfigurasi geogrid dan gabion yang kuat menopang timbunan setinggi 37 meter, dan memiliki faktor keamanan yang cukup terhadap beban statik dan pseudostatik. Untuk gabion mengacu pada SNI 03-0090-1999. Timbunan yang besar akan memiliki deformasi permanen ketika diberikan beban siklik gempa, sehingga harus diperhitungkan. Perhitungan manual dilakukan untuk mencari spacing dan panjang geogrid melalui konsep perhitungan tekanan lateral dan friksi. Perhitungan ketahanan atau keamanan dihitung dengan metode yaitu Element Hingga (PLAXIS 2D). Perhitungan Newmark Deformation dimulai dengan pembuatan Artificial Ground Motion spesifik untuk Sulawesi Selatan, dan mencari nilai percepatan gempa kritis sehingga didapatkan permanent deformation. Kategori desain Seismik mengacu pada SNI 1726-2012. Analisis deformasi diperhitungkan, kemudian menghitung mekanisme kedua material Geogrid dan Gabion. Analisis gaya internal geogrids dilakukan dengan melihat gaya maksimum yang dapat diterima per meter dibandingkan dengan gaya dalam pada PLAXIS 2D. Keluaran dari permodelan adalah konfigurasi geogrids dan gabion yang memiliki faktor keamanan diatas 1.5 untuk kondisi statik dan 1.1 untuk kondisi pseudostatik. Dari hasil perhitungan, didapatkan geogrid sepanjang 878 meter, dengan Gabion 42 dan permanent deformation 0.865 cm.Kata Kunci : geogrids and gabion, deformation, artificial ground motion, embankments tinggi

Full textAbstract:
Double-twisted hexagonal gabion wire mesh is a type of reinforced soil material that is used in gabion retaining walls to stabilize the soil slope in geotechnical engineering. In this study, a series of tensile tests were conducted to investigate the tensile behavior of hexagonal gabion wire mesh. Meanwhile, numerical models of gabion wire mesh were built to investigate the whole tensile loading-strain process. The influence of wire diameter, mesh width, and mesh length on the tensile strength of hexagonal gabion wire mesh were evaluated based on laboratory tests and numerical simulation. The quantitative relationship of tensile strength versus wire diameter, mesh width, and mesh length was typically fitted by a quadratic function, linear function, and monotonically decreasing exponential function. The numerical result presents a good consistency with those obtained from the experiment. The result of the loading-strain curve obtained by both experiment and simulation exhibits an “S” shape with a distinct serrated characteristic. The loading-strain curve can be divided into the following four stages: mesh distortion stage, wire stretching stage, overall yield stage, and wire fracture stage, which well reflects the tensile behavior of double-twisted hexagonal wire mesh. The tensile behavior of gabion wire mesh is influenced by the structure pattern of wire mesh and the mechanical characteristic of steel wire.

Full textAbstract:
The interface friction mechanics of reinforcement material with filler is an essential issue for the engineering design of reinforced soil structure. The interface friction mechanics is closely associated with the properties of filler and reinforcement material, which subsequently affects the overall stability. In order to investigate the interface mechanism of a double-twisted hexagonal gabion mesh with a coarse-grained filler derived from a weathered red sandstone, a large laboratory pullout test was carried out. The pullout force–displacement curve was obtained by fully mobilizing the gabion mesh to reach the peak shear stress at the interface between the gabion mesh and the coarse-grained filler. The change of force–displacement characteristics and the distribution of tensile stress in gabion mesh during the pullout process were obtained. A 3D numerical model was established based on the pullout test model, and the model for analyzing the interface characteristic between the gabion mesh and the coarse-grained filler was modeled using the FLAC3D 6.0 platform. The interface characteristics were further analyzed in terms of the displacement of soil, the displacement of reinforcement, and the shear stress of soil. The strength and deformation behaviors of the interface during the entire pullout process were well captured. The pullout force–displacement curve experiences a rapid growth stage, a development transition stage and a yielding stabilization stage. The critical displacement corresponding to peak pullout stress increases with the increase in normal stress. The normal stress determines the magnitude of shear stress at the reinforcement and soil interface, and the displacement distribution of a gabion mesh is not significantly affected by normal stress when the applied normal stress is within a range of 7–20 kPa. The findings are beneficial to engineering design and application of a gabion mesh-reinforced soil structure.

In this research, woven waste tire stripes are proposed as an alternative material to wire mesh to make a gabion wall. The performance of the waste tire stripe-based gabion wall is highly dependent on the strength of its stripe, where the stripe connector plays an important role. This research aims to inspect the behavior of different stripe connectors for the gabion wall. To achieve this, a physical model was built and employed to test the strength of the gabion wall. Various stripe connectors are used; adhesive rubber glue, one inch nail, and two mm wire. The strength capacity of the models was determined from the maximum stress before failure. The strength capacities of the models are 83.197, 59.426 and 62.397 kPa for the wire, nail, and glue connector, respectively. Hence, it can be inferred that the wire connector is the strongest of the three connectors.

Full textAbstract:
In the implementation of the St. Batu Tulis – Lintas Bogor – Sukabumi STA 5+550 project, a significant challenge arose with the occurrence of an avalanche during construction, attributing landslides to substantial land subsidence caused by the destabilization of the slope's soil or rocks. This disruption significantly impacted construction planning, particularly in terms of cost considerations. This study conducted a comprehensive comparative analysis of the stability of the original embankment slope and slopes reinforced with gabions (measuring 2m x 1m x 0.5m), sheet piles (type W-400 A-1000), and bored piles (size D600). To evaluate the stability, it was imperative to determine the safety factor (SF) and slope deformation under applied loads. The Plaxis 8.6 program was employed for the analysis, incorporating all relevant soil parameter data. Safety factor values were calculated as 1.67 for the gabion-bored pile combination slope, 1.62 for the sheet pile-reinforced slope, and 1.63 for the bored pile-reinforced slope. Estimated costs for slope strengthening were as follows: IDR 3,525,789,199.92 for sheet piles, IDR 2,180,309,258.00 for bored pile-gabion combination, and IDR 6,689,603,822.00 for bored piles alone. The budget for slope reinforcement with gabions proved more economical by IDR 1,345,479,941.92 compared to sheet piles and IDR 4,509,294,564.00 compared to bored piles. The reinforcement type selection was based on a cost analysis, prioritizing lower expenses while ensuring construction feasibility. Gabions offer advantages such as economical prices, flexibility, and simple construction methods, but they have drawbacks, including susceptibility of galvanized coated wire to water conditions with high salt or acid content and requiring a wide area for construction due to their large size. Sheet pile reinforcement is resistant to corrosion, durable, and has good performance, but it is unsuitable for supporting very high soil due to the requirement of a large cross-sectional area and not suitable for use in rocky soils due to piling difficulties.

This study presents the application of woven waste tires as slope reinforcement for preventing slope failure, reducing construction costs and minimizing environmental hazards associated with the increasingly large amount of waste tires in Indonesia. To this end, we performed laboratory experiments using five stripe distance variations of woven tires - i.e. 3, 4, 5, 6, and 7 cm as ribs of a gabion wall. Five gabion wall samples sized 50 cm x 50 cm x 25 cm each were made. Each sample was fastened using one of these woven tires. A loading test was conducted on each gabion wall sample and the strength was determined from the maximum capacity before failure. The correlation between the gabion wall strength and strip distance - boulder diameter ratio was used to infer the most effective model. The result suggests that the strip distance - boulder diameter ratio of 0.4 is optimum with a corresponding strength value of 1718 kg.

Coal mine backfilling can effectively prevent large-scale movement of rock formations, not only improving the overall production capacity of the mine but also protecting the surface from destruction and maintaining the original ecological environment. Backfilling extent and backfills compactness are two factors determining the supporting effect on the overburdens in underground coal mines. To make full use of the aeolian sand as the backfill materials in underground coal mines in the desertification areas, Northwest China. Then, vibratory compaction was proposed to enlarge the compactness of these sand-gabion backfills by considering the limited working space. After that, the movement law of the sand particles during vibratory compaction, the influencing law of the vibratory parameters, and the gabion constraint on the ultimate compactness of the sand-gabion backfills were studied using the discrete element software PFC3D from the microscopic point of view. It was found that the aeolian sand particles are more likely to inter-squeeze under vibration than under static load. Furthermore, there are a series of optimal vibratory compaction parameters to the inner aeolian sand for each external gabion constraint strength. The optimal vibration parameters were frequency 50 HZ, excitation force 0.3 MPa, amplitude 40 KPa, and vibration time 4 s. Conclusions of this study can provide references for enlarging the compactness of the sand-gabion backfills in the underground goaf in the desertification area of Northwest China.

In Brazil, hydroelectricity represents close to 70% of the energy consumed in the country. However, hydroelectric plant operations may be affected by the deposit of sediments for erosive processes on reservoir margins. This study presents the results of implementing two semi-rigid erosion control techniques installed on reservoir margins of two Brazilian Hydroelectric Power Plants (HPPs). These techniques were the gabion and gabion mattress used as a mixed technique and geogrid mattress technique. This paper highlights the importance of implementing geotextiles in the construction process of these erosion control techniques, taking advantage of their separation properties. The performance of the techniques was evaluated using qualitative performance variables and by differential bathymetry studies performed in 2016 and 2020 in the experimental units installed in each HPP. Moreover, the degradation of the geotextiles in each installation was evaluated through thermal analysis. The erosion control techniques that showed the best results were gabion and gabion mattress. Regarding the exhumed geotextiles, thermal analyses have shown that the commercial geotextiles that were used can withstand temperatures of up to 200 °C leading to no changes to their structure.

In the 2015 earthquake in Gorkha, Nepal, damaged different kinds of structures around the Kathmandu Basin. On the other hand, in mountainous areas, it was confirmed that gabion structures such as retaining walls along roads showed their high flexibility by performing their functions. In this paper, based on the results of the damage field survey on gabion retaining walls, a full-scale shake table test is conducted to evaluate the earthquake resistance of gabion retaining walls on roads, which are a common site in Nepal. The soil container used for the full-scale shake table test has the following internal dimensions: 4.0 m height, 3.1 m width, and 11.5 m depth. Earthen bank retaining walls with height of 3 m were arranged in three rows in a perpendicular direction to the cross-section, and the ground behind the retaining wall was prepared. The sinusoidal waves of 3 Hz were applied, consisting of 2 s of gradual increase, 4 s of steady part, and 2 s of gradual decrease; the input waves were provided in four stages of acceleration amplitude. Three types of gabion retaining walls were considered, i.e., vertical-type, stepwise-type and gravity-type, and 3D terrestrial laser measurement was conducted before and after shake table test of each case. Comparison of the residual deformations of the gabion retaining walls measured by 3D terrestrial laser showed that the vertical-type wall did not collapse but tilted forward after the shake teble test. A similar damage situation was confirmed by the field survey in Nepal. The other two cases suffered only slight deformation and are considered to be effective structures for application on sites. Finally, the trial wedge method was applied to the experimental results of the vertical-type of gabion retaining and useful suggestions for future earthquake-resistant design were made by comparing the active collapse angle with the positions of deformation, such as cracking which occurred in the ground behind the retaining wall after shaking. Then, the applicability of trial wedge method and its problem in the design of gabion retaining wall were shown.

Recently, the sound reflection index of a gabion wall was determined by means of the in-situ measurement method leading to unexpected results. An in-depth analysis was made of the results of the in-situ measurements on a conventional noise barrier and on a gabion wall. The main conclusion of this comparison is that application of the in-situ method on a gabion wall has a much higher measurement uncertainty than to be expected.

Abstract Panjang Island is a small island in Jepara, Indonesia which is very vulnerable to coastal damage due to crashing waves. Therefore, presence of coastal protection structure is essentially important. Gabion structure was constructed to protect this coastal area. Considering the age, the existing gabion structure needed assessment and analysis to ensure its performance in term of protecting the coastal area. This study aimed at assessing and analyzing the performance of the existing gabion structure. Data of the study were collected through observing the condition of the structure. Assessment was carried out by scaling 1 (minor) to 5 (severe damage). Results of the analysis showed that the value of stability to overturning was 3.96, while the stability to shearing was 2.07, the structure stability was in safe category. Soil pressure under the structure in σ max. was 0.39 kg/cm2, while σ min was 0.16 kg/cm2, which means safe. The condition of gabion as a coastal protection structure in section 1 was partially damaged with a moderate level of damage, in section 2, the damage was revealed to be a minor level of damage, while in section 3, the damage was in a minor level of damage.

Flooding has been natural disaster in Indonesia and elsewhere. This research is designed to create scenarios and designs conservation to mitigate flooding disaster. Data potential ,vulnerability, and duplicated river covering 0.25% of the targeted flooding area were collected and analysed. Five disain of conservation, natural river as control, river normalization, normalization with gabion stone, river straigtening, and straigtening with gabion stone, are proposed, and main targeted responses of these five scenarios are river current velocity. Effectiveness scenarios were analysed using Anova and Tukey test. The results showed that alignment with gabion stone was the most effective scenario for flooding mitigation since this was the most effective in increasing river current velocity. This could prevent riverbank occurrence of avalanche, accelerate river current, overcome flooding, and prevent future flooding. Other scenarios likes dead clicth ended-hallway, canalization, and riparian reclamation are also possible implemented.

Debris flows occur in multiple surges. Boulders entrained within the flow have been reported to incapacitate structures within its flow path. Single-layer cushions, such as gabions, are often installed to shield debris-resisting barriers from boulder impact. However, most relevant works only focus on single impact and the performance of gabions subjected to successive loading is still not well understood. A new large-scale pendulum facility was established to induce impact energy of up to 70 kJ on an instrumented rigid barrier shielded by 1 m thick gabions. The response of the gabions under six successive impacts was investigated. Results show that the peak boulder impact force given by the Hertz equation is at least four times the measured values. The recommended load-reduction factor (Kc) used in practice can be reduced by a factor of two. After six successive impacts at an energy level of 70 kJ, the transmitted force increases by up to 40%. Based on the Swiss guidelines, a 13% increase of gabion thickness is required when successive impacts are concerned. The results presented in this paper will be useful for practitioners designing rigid barriers.

Full textAbstract:
In this study, a structure that can effectively prevent overtopping caused by abnormal rainfall was installed in a deteriorative agricultural reservoir, and seepage characteristics were compared and analyzed through model experiments and numerical analysis. The experimental conditions were observed by installing a stepped gabion, vertical gabion, and parapet in combination with a gabion retaining wall, geomembrane, and core on the dam crest. Small horizontal and vertical displacements without defects were found, such as overturning and failure, to effectively prevent overtopping. A comparison of seepage line and pore water pressure results indicates that the seepage water drained smoothly to the toe drain through the filter from the upstream slope. It was perceived that the concentration of seepage water on the upper part of the dam crest might cause leakage to the upper part of the downstream slope and affect the stability of the overtopping prevention structures. The distribution of the hydraulic gradient was found to be stable in all cases on the downstream slope. The upper part of the downstream slope could be vulnerable to leakage, so careful management is required when constructing the geomembrane. Overall, among the three overtopping prevention structures applied, a stepped gabion retaining wall did not cause such problems as overturning and leakage. Therefore, it is considered better than the other types of overtopping prevention structure.

Abstract. The shores of seas, lakes, bays and reservoirs under the action of wind waves, drifting level ice, rainwater, wind erosion and other factors are subject to intensive destruction. As a result of this, the areas of valuable agricultural land and other lands are reduced. The destruction of the coasts is accompanied by landslides, which reduce the area of settlements where residential buildings, urban buildings, industrial enterprises, park areas, roads and other communications are located. In such cases there is a need for the construction of special protection structures, which will protect coasts from destruction. There are two methods of coastal protection ‒ active and passive. Experience in coastal protection shows, that in many cases, these methods can be successful when applied jointly. The types of structures of shore protection structures are diverse. Therefore, the main task of designers is to choose the most optimal of them, taking into account the climatic, hydrological and engineering-geological conditions of the region construction. The aim of this work is to create a progressive method of construction of shore protection structures on shallow shores of the seas and in shallow reservoirs. This paper considers the existing and innovative designs of shore protection structures made of various materials, the conditions of their use and technical and economic characteristics are analyzed. Based on the analysis, a progressive method of construction of shore protection structures from gabions is proposed. The using of the proposed method for the construction of shore protection structures from a box type gabion will speed up the construction process of such structures, as well as reduce the volume of material at the base, which will lead to a significant reduction in the cost of construction. The mass of gabions in each project should be determined on the parameters of the waves of the design storm in accordance to the recommendations of standards.

With large areas of water reservoirs and lakes, the wave runoff distance is also large, resulting in the high waves in the wind blow direction. These waves intensively disrupt the coast of the lake or water reservoir. Another intense factor of coastal erosion is ice. A lot of engineering measures for the coastal protection of reservoirs and especially for lakes are used: reinforced concrete slabs, blocks, jibs, cellular systems (geosynthetics), etc. An eroded coastline, reshaped by installing a coastal protection structure using gabion construction, is analysed in this research. Gabions are designed to protect banks and slopes from fast water flow (water speed over 5 m·s–1) and ice impacts. They are designed according to geotechnical principles, assessing stability according to the limit design situations specified in Eurocode 7 (EN 1997-1). The aim of this work is to illustrate the features of wave and ice loads and geotechnical design situations evaluated in the design of a coastal protection structure made of gabions.
