The course of rock mechanic is an engineering subject with very strong practicality; the combination of rock engineering, experimental model and theoretical model has considerable effects on its teaching quality. The achievement of high-performance computing technique based on soft and hard platform is employed in teaching rock mechanics. The rock engineering, experimental model and theoretical model are numerically investigated subtly. We encouraged students to design the numerical model and conduct the numerical study, which effectively help students to understand the elementary knowledge, foster their creativity, develop their basic research capacity, and expand their thinking extension and depth. With the popularization of high-performance computers, the investigation can provide significantly meaningful guides for the teaching of rock mechanics course in practice.
