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.

In this short video we demonstrate the hydraulically controlled cell lift on our 250kN load frame. The lifting mechanism allows users easy access to the sample without the need for an external lifting frame.

Diogo Teles a QA, Support and Installation Engineer from GDS Instruments, has recently returned from ITB Bandung in Indonesia, where he installed a GDS Enterprise Dynamic Triaxial Testing System (ELDYN).

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.
