Estimation of hydraulic conductivity of unsaturated soils under entire suction range
The hydraulic conductivity of unsaturated soils controls their water flow. Most numerical softwares adopt the hydraulic conductivity function (HCF) as the input parameter to simulate the water flow in unsaturated soils.

A numerical technique for modeling the behavior of single piles in unsaturated soils [PDF]
Pile foundations are widely used in both saturated and unsaturated soils. In certain scenarios, these foundations are subjected to combined vertical and lateral loads.

Volume changes take place during the fully undrained compression tests on unsaturated soils. It is more difficult to simulate the undrained mechanical behaviors of unsaturated soils than those of saturated soils.

Unsaturated soil is a form of natural soil whose pores are filled by air and water. Different from saturated soil, the microstructure of unsaturated soil consists of three phases, namely, the solid phase (soil particle), vapor phase, and liquid phase ...

UH model for ideal expansive unsaturated soils
The expansive unsaturated soils are characterised by the behaviour of volume increase and strength reduction during wetting, which may cause nonuniform foundation settlement and further result in cracking of overlaying buildings.

Unsaturated soils in the context of tropical soils
Abstract The practice of geotechnical engineering in tropical climate regions must consider the use of unsaturated soil concepts. However, these concepts must also take into account the specific behavior traits of tropical soils, particularly those related to soil aggregation, pore structure, and mineralogy.

Strength Theory Model of Unsaturated Soils with Suction Stress Concept
A theoretical model is developed for describing the strength property of unsaturated soils. The model is able to predict conveniently the strength changes of unsaturated soils undergoing repeated changes of water content. Suction stress is adopted in the
