| Abstract: | As one of the geological hazards, rockburst is often met in underground engineering under excavation unloading conditions in high geostress areas. According to the actual mechanics conditions, the triaxial test is designed to simulate the excavation of tunnel in this paper. The rock deformation-failure characters and mechanics mechanism of rockburst are also discussed. |
