Impact of Suction on the Near Surface Lateral Soil Response using Centrifuge Modeling [PDF]
E3S Web of Conferences, 2023 Recent studies have shown that unsaturated soils lead to greater lateral pile capacity. This study aims to experimentally assess how suction stress affects the lateral response of piles in unsaturated cohesionless soil.

A Unified Two Independent Stress Variable Approach to Moisture-Change-Induced Unsaturated Soil Volume Change [PDF]
E3S Web of Conferences, 2023 In 1968, Matyas and Radhakrishna introduced the concept of the state surface, demonstrating that unsaturated soil volume change is dependent on two independent stress state variables, net total stress and suction.

Effect of the optimum and residual moisture content on the strength characteristics of unsaturated sands [PDF]
E3S Web of Conferences, 2023 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.
