The rock mechanics experiment course is a practical course set up to supplement the rock mechanics theory. Combining with the postgraduate training plan of civil engineering major of the college, taking the teaching project of rock mechanics public experimental course as an example, starting from the background and purpose of the course, the teaching system of the experimental course, the construction process of the course content, and the teaching method adopted by the experimental course are expounded. and teaching methods, and built a teaching quality assurance system. Finally, it summarizes and thinks about the teaching construction mode of the experimental course, and puts forward several points that need to be improved in the later construction of the course teaching. The results show that the implementation plan of the experimental course construction is feasible, the construction results can be better applied to the specific practice of postgraduate courses, and the in-depth development in the later stage can improve the education quality of postgraduates majoring in geotechnical engineering in our college, and to some extent can promote the discipline construction and development.
