| 英文摘要 | A new rock deterioration model is presented to simulate both the brittle failure activity of hard rock and deterioration of material mechanical parameters in wall rock of underground engineering. The model has three basic characters: (1) The stress-strain curve composes of liner elastic part, stress falling part and plastic flow part; (2) The mechanics parameters is updating with the deteriorating of rock mass in the excavation damage zone; (3) It can simulate the uneven distribution of material property. Fitting rock triaxial compression test stress-strain curve of granite and simulating experimental tunnel identify that the model is reasonable. |
