an investigation of swell-shrink behavior of an expansive soil
expansive soils show swelling and shrinkage behavior when subjected to cyclic wetting and drying. the variation in water content influence the volume change in this kind of soil. these volume changes can cause ground movement which may result in damage to the buildings and structures. to study the behavior, a number of successive wetting-drying cycles were conducted on a statically compacted ex...
متن کاملswell- shrink behavior of expansive soils under different surcharge and water qualities
expansive soils are of the kind the volume of which will be changed to extremes by being exposed to varying conditions of moisture. this volume change is a serious menace to structures built on these types of soils. throughout the present research the potential of volume change in these soils was investigated when exposed to the phenomenon of wetting and drying. for the purpose, samples of a st...
متن کاملThe Effect of Wetting-Drying Cycles and Plasticity Index on California Bearing Ratio of Lime Stabilized Clays
This paper aims to present an experimental and numerical study on the effect of wetting-drying cycles and plasticity index on the California Bearing Ratio (CBR) of lime stabilized clayey soils. The numerical analysis was carried out based on finite element method for comparison between results of experimental and numerical studies. Three clays with different plasticity indices were mixed with v...
متن کاملTreatment of expansive soils with quality saline pore water by cyclic drying and wetting
Expansive soils can be found in many parts of the world particularly in arid and semi-arid regions. These soilspose a significant hazard to civil engineering structures due to its high swelling and shrinkage potential. This paperpresents the results of an experimental program developed to investigate the effect of cyclic drying and wetting on theswelling potential of expansive soils with variou...
متن کاملChemical Amelioration of Expansive Soils
Expansive soils swell when they absorb water and shrink when water evaporates from them. Hence, lightly loaded civil engineering structures founded in these soils are subjected to severe distress. Therefore, there is a need to ameliorate or improve these swelling soils through some innovative methods. This paper discusses chemical stabilisation of expansive soils, a technique in which chemical ...
