Since every potential failure scenario might result in significant losses in both lives and property, the construction of dams needs extensive research to ensure the safety and feasibility of these large engineering structures. In this article, the Analyses should be performed upon specifically to evaluate seepage, slope stability, and soil liquefaction of significant earthen dam. A numerical technique employing the finite element method (FEM) was used in this article. Finite element software (GEO-STUDIO 2022) was used to carry out both steady-state and transient seepage analyses and pseudo-static ground motion That deals with the present work behavior of the Narasimharaya Sagar (Gorakallu Balancing Reservoir) earthen dam which is in the earthquake prone area of Zone II (as per IS 1893-2002).Geostudio 2022’s SLOPE/W, SEEP/W, and QUAKE/W tools examine the stability characteristics slope, seepage, and earthquake (finite element modelling based software). The model with the reservoir at full capacity is initially examined using SEEP/W to identify the piezometric line, which serves as the foundation for SLOPE/W to determine slope stability. Afterwards, it is exposed to a 0.1 peak ground acceleration earthquake motion using QUAKE/W to know its dynamic stability.

Malalak is one of the youngest sub-districts in Agam Regency, the district was previously included in the administration of the district IV koto. Malalak sub-district officially separated its elf into its own sub-district on May 24, 2007. Simalaka Road (Sicincin-Malalak-Balingka) connects between Balingka nagari in district IV Koto, Malalak nagari in Malalak sub-district, and Tandikek nagari, Patamuan, Sicincin in Padang Pariaman district.This study is classified into applied research. will use soil parameter and rainfal to find out, and analyze the extent of rain characteristics on slope collapse, as well as compare the safe factors obtained using fellenius medote and Geo-studio V Software, due to disturbed soil stability or slope building rocks.In determining the value dari the safety factor of the slope by using software Geo-Slope /W obtained the value of safety factor is 0.70. The result of vibrational influence as well as the frequent rain stability of the slopes experienced a considerable decrease in the safety value of the slopes and showed that the slope conditions unstable. Analisis safety factor from research conducted on malalak road section KM 31 can be summed up a few things as follows. From the analysis obtained a definition of the factors that cause slope unstableness. From the calculation results can be that rainwater infiltration is very influential to the stability of the slope, where safety factors or FK (Safety Factor) slopes decrease along with the length of rainwater infiltration that occurs in the area especially during the soil hoarding process occurs, this can be seen from the results of geostudio analysis and fellenius method that shows reduced slope safety factors.

Cofferdam is a building in the form of earth, stone, concrete or masonry filling and holds water, prevents flooding, provides irrigation. The building has many functions such as for agriculture, power generation, and tourist attractions. Cofferdam will also be very helpful in flood control which will control flood water so that it will not overflow excessively which endangers the surrounding community. Besides having great benefits. If the cofferdam collapses (broken) it will cause flash floods that result in casualties. Therefore the cofferdam must be designed safely and technically feasible. The research approach used in this study is a quantitative approach using the 2012 GEO-SLOPE program. The conclusions from the analysis of slope seepage and seepage stability are the Critical Safety Factors for cofferdam stability according to the results of the analysis after running SLOPE/W are 1.711 & 1.512 because it is higher than 1.5 (SNI 8460:2017 Geotechnical Requirements Design, This means that the stability of the cofferdam is safe. The modeling results show that the seepage discharge is 1.81x10-7 m3/s = 1.81x10-4 liters/sec = 15.64 liters/day which is smaller than the maximum allowable discharge of 50 liters/day. So it can be concluded that the seepage discharge is safe.

Testo completoAbstract (sommario):
Slope failure is a common phenomenon all over the world on both man-made and natural slopes. Prolonged rainfall is one of the climatic factors which is largely responsible for slope failure. During heavy and prolonged rainfall, a part of the rainwater infiltrates through the soil and seeps into the slope. The infiltrated water lowers the matric suction and increases the porewater pressure. Eventually, the generated porewater pressure decreases the strength of the soil which results in slope failures. To evaluate the effect of rainwater seepage on slope stability, it is necessary to investigate the hydraulic conductivity of the slope soil. The objective of this study is to evaluate the effect of hydraulic conductivity on slope failure mechanisms. A finite element analysis of slope stability was conducted using Geo-Studio software. A numerical model was developed and calibrated with field monitoring data. The field monitoring data included the observation of hydraulic conductivity using a Guelph Permeameter. Afterward, the temporal variation of rainfall and hydraulic conductivity was incorporated into the SEEP/W program and the consequent changes in slope stability were evaluated in SLOPE/W. From the numerical analysis, with the identical strength parameters of the soil, different factors of safety were observed when the slope sections retain different hydraulic properties. Based on the numerical analysis, it was observed that hydraulic conductivity greater than 4×10-6 cm/s leads to slope failure. Periodic monitoring of hydraulic conductivity in the field may provide deep insight into rainfall-induced slope failures.

Evaluation of slope stability under water level fluctuations is an important topic in the Three Gorges Reservoir (TGR) in China. However, most of the previous studies regarded slope soil as isotropic material, or only considered the influence of anisotropy ratio (kr = kx/ky) but ignored the anisotropy direction (α). Meanwhile, the pore pressure–stress coupling was rarely considered in the previous numerical simulations. In the present study, the SIGMA/W and SLOPE/W modules in Geo-studio are utilized to carry out the numerical simulation of Caipo slope under the drawdown of the reservoir water level, and the anisotropy ratio (kr) as well as the anisotropy direction (α) of two kinds of soils (clay and sand) are included. Results show that the anisotropy ratio kr and anisotropy direction α decrease the infiltration capacity of the soil, which increases the infiltration line hysteretic elevation (ILHE) as well as maximum horizontal displacement (MHD), and reduces the minimum safety factor (MSF). The slope toe firstly fails with the drawdown of water level. The influence of reservoir water level drop on seepage, deformation, and stability of the sand slope is less than that of the clay slope. For the sandy soil slope, it is not only necessary to consider the influence of kr, but also the influence of α. For the soil slope, we can only consider α in order to simplify calculation.

Evaluation of slope stability under rainfall is an important topic of Geotechnical Engineering. In order to study the influence of anisotropy ratio (kr = kx/ky) and anisotropy direction (α) on the seepage and stability of a slope, the SEEP/W and SLOPE/W modules in Geo-studio were utilized to carry out the numerical analysis of a homogeneous slope in Luogang District, Guangzhou City, China, which is based on the theory of unsaturated seepage and stability. Two kinds of soils (clay and sand) were included. Results show that: For sandy soil slope, the increase of kr promotes the rainfall infiltration, and the decrease of α prevents the rainfall infiltration. The maximum water content of the surface (MWCS) reaches maximum with the increase of kr and α. The rising height of groundwater (RHG) is −3–4 m and the safety factor (SF) is 1.3–1.7. For clayey soil slope, variations of kr and α have little impact on the seepage characteristics and slope stability. The MWCS remains almost the same. The rainfall infiltration depth (RID) is 0.5–1 m and the SF is about 1.7. Therefore, for sandy soil slope, it is not only necessary to consider the influence of kr, but also the influence of α. For clayey soil slope, it can be treated as isotropic material to simplify calculation.

An offshore breakwater is designed for the construction of a LNG-terminal. For the slope stability analysis of the rubble mound breakwater the existing and the extreme wave climate are considered. Pore water pressure variations exist in the breakwater and its permeable foundation. A wave trough combined with the moment of maximum wave run-up results in a decrease and increase of the pore water pressure, respectively. Therefore, the wave actions have on overall effect on the slope stability of the breakwater. To include the wave actions in the slope stability analysis a simplified method is used. For the slope stability analysis, a specific piezometric line is determined. This piezometric line consists of a wave profile and the profile of wave run-up. The slope stability analysis are performed with GEO-SLOPE/W 2007. For the geotechnical design of the breakwater load cases of extreme and normal waves combined with, respectively, extreme and normal water levels are analysed. All the load cases which included the wave actions result in lower stability safety factors than the load cases with only still water levels. Therefore the wave actions are the determining load case for the geotechnical stability of the breakwater and it should be studied in detail.

Water leakage through the earth dam and the foundation is an important phenomenon that must be considered when designing earth dams, as it generates pore water pressure and causes internal erosion of the dam material that affects the stability of the dam by generating stresses and strain in it. There are a variety of technical methods available to minimize these concerns, such as using core, horizontal filter system, or by modifying the dam's geomatics specifications. The current study observed that at steady state flow through earth dam with horizontal filter, core, and no filter. Increasing the slope of the upstream dam reduces the amount of pore water pressure inside the dam body, while the maximum increase in pore water pressure occurs in the case of no filter. Furthermore, the highest stress at the dam's base is increased by the decrease in upstream slope. Furthermore, the dam's upstream slope has a significant effect on the values of the vertical and horizontal displacements created with in dam. Since the presence of the core generates the greatest increase in the horizontal displacement of the dam and foundation section. Changing the permeability coefficient of the dam body also produces a modification in the stresses at the dam's base by about ± 2%. Also, when utilizing the core, there is the lowest increase in seepage discharge, however when using the horizontal filter, there is the greatest rise in discharge (53.78 %) compared to the case without a filter. Furthermore, while using a horizontal filter, the percentage increase was (1.13%) as compared to when no filter being used
