Case Study: Northeastern University, GDSTTA

To simulate the complex multi-axial stress conditions of rock, a customized GDS True Triaxial Apparatus for rock was manufactured for Northeastern University.

Engineering activities such as underground mining and large excavation of unconventional resource, are all potentially liable to induce engineering disasters such as earthquake, rockburst and large-scale collapse. The rock mass in the earth's crust are usually subjected in the true triaxial stress state (Feng et al, 2016), but the majority of existing rock testing apparatus can only simulate the conventional triaxial stress state, which is not in accord with the actual stress state of rock mass.
