Course Description

In this course, we will give lectures on the physical properties and mechanical properties of rocks under large depths, in-situ stress, stability of underground spaces such as radioactive waste disposal and traffic tunnels.

Grading

Course Goals

Understand the representative physical properties of rocks under high temperature and high pressure, measurement methods of in-situ stress and their applications in radioactive waste disposal and traffic tunnels.
