Lateral dynamic response of pile group embedded in unsaturated soil

, 2021
A mathematical formulation is proposed for the analysis of a pile group embedded in unsaturated soil subjected to horizontal time-harmonic vibration. The unsaturated soil is governed by the motion theory of three-phase poroelastic medium, and the piles ...

Estimation of wetting hydraulic conductivity function for unsaturated sandy soil

, 2021
The occurrence of rainfall-induced slope failures is mainly due to the infiltrated rainwater which reduces the shear strength of soil. The slope is initially observed in an unsaturated condition and it becomes wetted during rainfall.

Effects of wetting-drying cycles and desiccation cracks on mechanical behavior of an unsaturated soil

, 2020
The effects of wetting-drying (W-D) cycles on the desiccation-induced cracking of a fat clay (CH) as well as the role of soil suction in the evolution of soil strength, were investigated.

A novel model of heat-water-air-stress coupling in unsaturated frozen soil

, 2021
The accurate prediction of frost heave in unsaturated frozen soil is crucial for the construction and protection of projects in cold regions. The occurrence of frost heave in unsaturated frozen soil is accompanied by an extremely complicated process of ...
