The determination of the shear strength of unsaturated soils is generally more complicated, time consuming and expensive compared to the determination of the shear strength of saturated soils. Although much res

However, the impacts of loading rate on the undrained shear strength of unsaturated soils may be more complicated than in saturated soils due to the effects of matric suction and degree of saturation on the stress state, effects of compaction, generation of shear-induced excess pore air and ...
It is well understood that rainfall infiltration decreases the unsaturated shear strength of soil slope due to reduction in matric suction as the wetting front moves through it. However, how much the matric suction is reduced that may affect slope stability results is still unknown. The paper ...

A similar behavior was determined in unsaturated soils21. Soil compressibility is both stress- and temperature-dependent19. Higher temperatures typically imply larger volumetric and shear strains but lower plasticity and water retention capacity22, partly owing to the smaller viscosity of the pore water...
