Construction and Programming of Bivariate Model for Unsaturated Soil Seepage Calculation
Frontiers in Earth Science, 2022 The seepage calculation of unsaturated soil has always been an important subject in the field of geotechnical engineering, and it greatly influences the stability of geotechnical engineering.

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 ...

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

Practical Approach for Assessing Wetting-Induced Slope Failure
Applied Sciences, 2023 Ignoring the role of soil suction and implementing unsaturated soil mechanics when assessing slope stability in Indonesia is a common practice. One of the main reasons is due to the precognition that incorporating soil suction means using higher shear ...
