Estimation of the shear modulus of unsaturated soils using the capillary model [PDF]
Scientific ReportsThe shear modulus is a fundamental parameter for evaluating soil deformation and stiffness. It is influenced by various factors, including void ratio, confining pressure, soil type, and soil suction (or degree of saturation).

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.

Design of an automated tension infiltrometer for unsaturated hydraulic conductivity measurement [PDF]
, 2006 A tension infiltrometer for field use, where both water level changes measurement and tension settings could be automated, was built in-house. Differential pressure transducers were used to automate the water level measurement in the reservoir.

Identifying true shrinkage limit of clay by updating experiments in Chinese standard GB/T 50123—2019
Yantu gongcheng xuebao, 2022 The methods to determine the true shrinkage limit of clay are proposed by updating both the testing procedure and the data processing of the shrinkage limit and shrinkage test methods in the Chinese standard for geotechnical testing method (GB/T 50123 ...
