An unsaturated soil is a state of the soil. All soils can be partially saturated with water.
Therefore, constitutive models for soils should ideally represent the soil behaviour over …

The coupled effects of changes in suction and stress on the response of unsaturated soils is
a fundamental aspect to consider when dealing with unsaturated soils. The difficulty of …

Unsaturated soil mechanics has rapidly become a part of geotechnical engineering practice
as a result of solutions that have emerged to a number of key problems (or challenges). The …

This paper proposes a new water retention model for unsaturated soils, which takes into
account capillary condensation of adsorbed water. In this model, the degree of saturation of …

Many shallow foundations are constructed within the soil layer above the groundwater table,
where the soil remains unsaturated, and the failure of shallow foundation is mostly related to …

This paper introduces a methodology to predict the non-linear stiffness–suction and shear
strength–suction relationships for unsaturated soils within the lower suction range from the …

In this paper, localized deformation in partially saturated sand was investigated
quantitatively using microfocus X-ray computed tomography (CT) and an image analysis of …

Shear strength is one of the fundamental properties of unsaturated soils. It has been found to
change with matric suction. Various shear strength equations have been proposed for …

The vapour equilibrium method and osmotic technique have gained widespread acceptance
as reliable methods for controlling relative humidity and thereby suction in soil specimens …

The degree of saturation (S) of soil can be separated into two components: the degree of
capillary saturation (S′) that is based on the capillary water and the degree of adsorptive …
