Abstract:

The damage mechanism of loessial soils was studied by the statistical theory.Based on the characteristics strength of loessial soils micro-unit with Weibull distribution, and parameters that described by distribution variable of Drucker-Prager creterion are used, loessial soils damage constitutive model considering damage threshold is established to reflect the full process of loessial soils failure. Conventional triaxial consolidation undrained shear test results of loessial soils are taken as example to verify the model. By comparing theoretical calculation results with test results, it is s

Abstract:

Banqiao school building had to be demolished for rebuilding because of severe damage induced by liquefaction following the 2008 Wenchuan Ms 8.0 Earthquake. The mechanism of the building damage and the characteristics of liquefied soils were investigated by trench, borehole drilling, and Dynamic Penetration Test. The detailed field investigation and in-situ tests show that: (1) The Banqiao school building suffered more severe damages than its surrounding buildings from the liquefaction rather than inertia force of shaking during the earthquake; (2) The subsurface liquefied soils are gravelly so

Abstract:

This paper presents the results of a comprehensive experimental program for investigating the influence of mechanical damage on the load-displacement behavior of geogrids. Unconfined tension tests, pullout and direct shear tests were carried out on intact and damaged specimens. Natural or artificial damages were produced either by imposing heavy compaction procedures in the laboratory or by simply cutting one or more geogrid elements. It is concluded that natural damage in the geogrid may be more pronounced when aggressive compaction methods are used with coarse grained soils. Fine grained soi

Abstract. In the Netherlands, subsidence of peat and clay soils due to (artificial) lowering of the groundwater table and loading of soft soils is commonplace, causing extensive damage to exposed and vulnerable assets. Awareness of subsidence-related damage to buildings has recently increased in the Netherlands, particularly after reported damages due to the 2018 extremely long dry period. However, despite this being a major concern to homeowners and public authorities, an integrated and systematic risk assessment on regional or national scale is currently lacking which inhibits concrete and m

Contaminated soils and their associated problems have increasingly become a matter of concern. The most common contaminants generated by industrial urban emissions and agricultural practices are trace metals. Remediation of trace metals is mostly conducted using physico-chemical processes and this causes soils to become polluted. Nevertheless, these techniques damage the soil’s biological activity and require highly sophisticated expensive equipment. Phytoremediation is a relatively low-cost technology based on the use of selected plants to remove, degrades or contains soil pollutants. The pot

Swelling soils cause serious damage to engineering structures, and they pose a problem worldwide. The fluctuation of water content is one of the most important factors that cause the swelling pressure of soils, especially for soils in arid and semi-arid regions. The swelling soils in these regions are exposed to cycles of volume increase and decrease in the rainy and dry periods. Thus, low-rise buildings and infrastructure constructed on or in these soils are exposed to potential damage.

Freezing and thawing of soils are common in cold regions. They may even be considered as limit states from the thermo-hydro-mechanical point of view. Thus, to characterize the behavior of freezing and thawing soils, some basic principles should be considered. Design to prevent frost damage should be based on theories that have been shown to apply to field conditions. The laboratory procedures used in the design should imitate the expected freezing behavior, and the tested specimen should be prepared to simulate the soil conditions in the field.

In United States during 1973, the annual cost of damage was $2.3 billion due to expansive soil movement. A more up-to- date it has reached up to $9 billion annual damages to different structures. This paper presents experimental study of California bearing ratio values of soil-fly ash mixtures and randomly distributed Nylon fibres. The effect of addition of Nylon Fibres on California bearing ratio values (CBR) is studied. The percentage of HT Nylon 66 Fibres content is considered as 0

Abstract. The aim of the study was to describe biochemical reactions in the soil based on the activity of urease and dehydrogenases in Scots pine stands damaged during and differentially managed after hurricanes. Soil enzymatic activity was investigated in 2005 and again in 2013 for selected stands in the Pisz Forest District where wind damage occurred in 2002. Most of the damaged stands were cut down and replanted, but 445 ha were left untouched for study purposes. The investigated areas differed with respect to stand damage and management. The enzymatic activity correlated well with the cont

Abstract:

Civil engineering structures such as buildings, highways, dams, canals and retaining structures, etc. suffer large-scale damage due volume change of expansive soils. To control the damage and to stabilize such expansive soils are some key challenges in the field of geotechnical engineering. The use of fuels as a soil stabilizer is one of the sustainable, environmental friendly and economical technique to improve the geotechnical properties of expansive soil. The fuels used in this study are crude oil and toluene. Free-swell tests and oedometric tests were carried out to investigate the effecti

Abstract:

Two South African sandy soils, one suppressive and the other conducive to ectoparasitic nematode damage on monoculture sugarcane, were compared. Analysis of field transects indicated that the suppressive soil displayed a comparatively higher population of the weak ectoparasite Helicotylenchus dihystera, whose predominance among ectoparasitic nematodes is known to limit yield loss caused by more virulent phytonematodes. Soil type was identical at both sites (entisols), but the suppressive soil had a higher organic matter content and a lower pH, which correlated with H. dihystera population data

Abstract:

There are many flaws, such as fissures, cavities, and inclusions, in geomaterials, which make their mechanical properties with great randomness and uncertainty. Upon loading, the soil structure gradually losses the bearing capacity due to the transformation from microdefects to macroscopic breakage bands. Based upon the experimental data of frozen sandy soils, a new nonlinear strength equation between the first and third principal stresses was proposed, and then the nonlinear strength properties for frozen sandy soils in σ-τ plane were analyzed. In addition, by assuming that the microstrength

A series of experiments was undertaken to examine the effect of soil type on the spatial distribution of greyback canegrub in sugarcane in the Burdekin region of Queensland. These experiments examined spatial distribution at a district level as well as within individual fields, using both field and laboratory experiments. The studies concluded that soil type affected canegrub distribution both within fields and within the Burdekin district. However, the mechanisms affecting the distribution at each level were very different. At a regional or district level the preference of greyback canegrub f

Abstract:

Near surface soils can greatly influence the amplitude, duration, and frequency content of ground motions. Surveys of the damage caused by earthquakes indicates that the lowest levels of damage occur in structures founded on rock or hard soil, while most of the damage occurs usually in structures founded in soft soil sites. With the aim to understand better the seismic response of soft soils deposits, not susceptible to liquefaction, this study made a comparison between the real seismic response registered in soft soil deposit in the 2011 Tohoku earthquake (Mw=9.1), with the response predicted

AbstractThe effects of trampling on six types of vegetation and their underlying soils were investigated on sub-Antarctic Macquarie Island. One hundred and fifty foot-passes per year for at least the past 10 years have occurred on a typical 6-km stretch of walking track on the island's upland plateau. Trampling favours vascular plants including exotics, especially Poa annua, while bryophytes and lichens are more common in undisturbed vegetation. The abundance of 19 of the 39 most common species appears to be affected by trampling. Track width is positively correlated with exposure and wet soil

Abstract:

Some Clayey soils are generally categorized as weak soils, and structures lying on such soils have been exposed to severe damage. Therefore, the central thesis of this paper is the impact of a waste material known as a silica fume as nano and micro material on soil’s behaviour. To evaluate the effects of those additives on Atterberg limits, compaction characteristics and unconfined compressive strength, clayey soil samples have been transformed using micro and nano silica fume (by-product materials). In the current investigation, silica fume is used at four different percentages: 0, 2, 4, and
