...Yan Liu; Xiang Wang; Yuxin Zhao; Lihong Chen; Xu Li Predicting the stress–strain behavior of unsaturated soils is essential for determining yield stress. This paper explores a new method for determining the yield stress of unsaturated soils from the lateral pressure curve. A series of earth...

...M. Ajdari; M. Monghassem; H. Reza Lari In this paper, an osmotic diaphragmatic oedometer was introduced to determine the hydromechanical behavior and the coefficient of lateral pressure of unsaturated expansive soils at constant suction values. Adopting the osmotic method to impose the matric...

... a newly developed oedometer with devices for controlling suction and measuring lateral pressure. The test results show that while both vertical swelling pressure and lateral pressure are path dependent, there are lower and upper values of mean effective pressure depending on initial soil conditions. Based...
