Hydromechanical behavior of unsaturated expansive clay under repetitive loading
Journal of Rock Mechanics and Geotechnical Engineering, 2021 Compacted layers of expansive soils are used in different engineering projects, such as subgrades, engineered clay barriers, and buffers for radioactive waste disposal. These layers are exposed to a variety of stresses and wetting conditions during field

Determining the unsaturated hydraulic conductivity of a compacted sand-bentonite mixture under constant volume and free-swell conditions [PDF]
, 2008 Highly compacted sand-bentonite mixtures are often considered as possible engineered barriers in deep high-level radioactive waste disposals. In-situ, the saturation of these barriers from their initially unsaturated state is a complex hydro-mechanical ...

Special Considerations in Design of Foundation in Problematic Soils [PDF]
, 2016 The ability of a structure to withstand stresses starts from the nature of the soil on which it is built and the suitability of the foundation adopted for the corresponding soil condition. There are different types of problematic soils mostly encountered
