A Numerical Model to Study the Response of Piles under Lateral Loading in Unsaturated Soils
Geosciences, 2021 The interaction between a laterally loaded pile and the surrounding soil is typically limited to the shallower soil layer. Often, this zone is above the water table and therefore the interaction takes place under unsaturated conditions.

An elasto-plastic model for unsaturated soil incorporating the effects of suction and degree of saturation on mechanical behaviour [PDF]
, 2003 The paper presents an elasto-plastic model for unsaturated soils that takes explicitly into account the mechanisms with which suction affects mechanical behaviour as well as their dependence on degree of saturation.

Applied Sciences, 2023 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 ...

Estimation of the hydraulic parameters of unsaturated samples by electrical resistivity tomography [PDF]
, 2012 In situ and laboratory experiments have shown that electrical resistivity tomography (ERT) is an effective tool to image transient phenomena in soils. However, its application in quantifying soil hydraulic parameters has been limited.

Unsaturated soils in the context of tropical soils
Soils and Rocks, 2021 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.

Cyclic behaviour of an unsaturated silty soil subjected to hydro-mechanical damage [PDF]
E3S Web of Conferences, 2020 The dynamic behaviour of unsaturated soil subjected to cyclic loading is considered using two stress state variables, net normal stress and matric suction. Though the influence of excess pore-water pressures in fully saturated soils has been investigated

Uncertainty in the determination of soil hydraulic parameters and its influence on the performance of two hydrological models of different complexity [PDF]
, 2009 Data of soil hydraulic properties forms often a limiting factor in unsaturated zone modelling, especially at the larger scales. Investigations for the hydraulic characterization of soils are time-consuming and costly, and the accuracy of the results ...
