| Abstract: | The failure of rock mass due to excavation unloading is a common phenomenon. However,classical strength theories can hardly reflect unloading failure of rock mass.Based on the damage mechanical theory,a damage constitutive equation of unloading failure of rock mass is established in the paper.A comparison of experimental test results shows that the model is in very good agreement with experiments. |
