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 …

An unsaturated soil is a three-phase material that is ubiquitous on the earth's surface. The
fully saturated and completely dry states are just two limiting conditions of an unsaturated …

The freezing process of salinized soil is a complex, dynamic, and interactive hydro–thermal–
salt–mechanical (HTSM) coupled physical phenomenon. In many recent studies, soil was …

Hydromechanical behaviour of unsaturated expansive soils is complex, and current
constitutive models failed to accurately reproduce it. Different from conventional modelling …

This paper proposed a series of simple equations to calculate the head difference at the two
sides of waterproof curtain. The barrier effect of waterproof curtain is considered from two …

Unsaturated soil behaviour, such as volume change, shear strength and yield stress, is
usually interpreted and modelled in terms of stress and suction. This approach is consistent …

This paper presents a simple approach to quantify the effect of initial soil density on the soil-
water characteristic curve (SWCC) of unsaturated soils. This approach is based on an …

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 …

This paper presents a hysteretic water retention curve (WRC) and unsaturated hydraulic
conductivity model for deformable soils based on the change in pore-size distribution (PSD) …

This paper presents an advanced constitutive model for unsaturated soils, using Bishop's
effective stress (σ′) and the effective degree of saturation (S e) as two fundamental …
