Abstract

New geotechnical challenges are encountered due to construction of new urban communities in desert, among which is dealing with collapsible soil formations. Collapsible soils are metastable material, traditionally defined as an unsaturated soil that experiences a radical rearrangement of particles and significant reduction of volume upon wetting. In this study, an experimental program is conducted to investigate the influence of various parameters on the collapse of reconstituted sandy soils. The magnitude of collapse of ten sandy soils containing different types and percentages of fines is determined using the single oedometer Test. All these soils are prepared at 35% relative density. Then, the effect of related parameters including silt content (10%–50%), type of fines (silt/clay), initial water content (5%–15%), and wetting pressure (0–200 kPa) have been studied. Furthermore, the initial matric suction is determined using the ASTM filter paper method in order to study its effect on the soil collapsibility. Finally, Scanning Electron Microscope (SEM) is used to visually examine the effect of fines on the collapse susceptibility of sandy soils.
