What is it about?

A dynamic-disturbance triaxial testing system for frozen rock specimens was developed in the CUMTB rock mechanics laboratory to characterize the evolution process of the instantaneous and long-term mechanical properties of frozen rock specimens under conventional and dynamic loading, with special attention to the deformation characteristics of rock under subzero temperature, dynamic disturbance and a three-dimensional (3D) pressure state.

Why is it important?

A series of conventional triaxial compression tests and triaxial loading creep tests of rock specimens under subzero temperatures and disturbance environments has been carried out. The obtained results, such as instantaneous deformation and time-dependent feature of frozen soft rock on complex condition, show that the capabilities of our system can be verified reasonably.


To solve the mechanical properties of frozen fractured and porous soft rock under disturbed environment, we have developed a new dynamic-disturbance subzero rock triaxial testing system.
