Unified Solutions for Unsaturated Soil Shear Strength and Active Earth Pressure
The unified solution for shear strength for unsaturated soil in terms of two independent state stress variables is presented based on both Unified Strength Theory (UST) and Fredlund's shear strength theory for unsaturated soil, which can be especially versatile in reflecting the effect of intermediate principal stress. Considering different distributions of matric suction, the unified solution of active earth pressure for unsaturated soil is deduced, which could avoid some shortages of Rankine's active earth pressure. The influence of the intermediate principal stress and matric suction on the active earth pressure is also investigated. It is shown that the active earth pressure decreases significantly with an increase in the unified strength theory parameter or matric suction.
