Case Study: Numerical Analysis, Design of Dams (Natural Soils, Tailings) And Deep Excavations

When performing stability tests for the purpose of designing dams and deep excavations, an essential component is the appropriate selection of strength parameters of soils. Due to the fact that on the shear surface we deal with, the principal stress direction rotates, it is important to determine the strength parameters for the compression and the extension loading conditions.

Case Study: Wenzhou University, GDSTTA

Soft clay is widely distributed in southeast coastal cities of China, such as Shanghai, Hangzhou and Wenzhou. It has been recognized as one of the most problematic soils in China because of its high water content, high compressibility, low permeability and low bearing capacity. In the past decades, a large number of infrastructure projects have been constructed on this kind of soil. After years of operation, large settlements of the subgrade have been observed.
