Effect of the optimum and residual moisture content on the strength characteristics of unsaturated sands [PDF]
Soil exists mainly in unsaturated conditions. Therefore, accurate prediction of the soil shear strength for unsaturated conditions also becomes equally important for the geotechnical design of earth structures.

Evaluation of oil pollution dispersion in an unsaturated sandy soil environment [PDF]
The current study assesses critical condition of oil dispassion, considering the unsaturated soil condition dispersity behavior for oil dispersion. The numerical model is used as a finite element method to model the oil spill pollution with two different

Numerical study on bearing capacity of a pile group next to a slope in unsaturated soils [PDF]
The bearing capacity of a pile group mostly depends on parameters of the soil shear strength affected by the soil-water characteristics, especially in unsaturated soils.

Active Soil Pressure of Unsaturated Soil under Rainfall Conditions
To study the change in unsaturated active earth pressure under rainfall conditions, based on the thin layer element method and shear strength formula of unsaturated soil, Iverson analysis was used to improve the traditional Coulomb earth pressure theory,

Benchmark of constitutive models for unsaturated soils [PDF]
The paper presents a collaborative piece of research undertaken by seven research teams from different universities within the ‘Mechanics of Unsaturated Soils for Engineering' (MUSE) network. The objective is to benchmark different approaches to constitutive modelling of mechanical and water retention behaviour of unsaturated soils by comparing ...
