A NEW NUMERICAL METHOD FOR MODELING ROCK MASS FAILURE
In recent years, many failure criteria have been proposed and used to predict the non-linear rock mass failure, among which strain energy density theory is currently widely applied considering a variety of factors. However, analytical solution is hardly suitable for engineering practice due to the complexity of the model and the stringent requirements of the boundary conditions. Therefore, a new numerical method for predicting the rock mass failure is presented in the paper. Based on the strain energy density and the energy dissipation theory, the element failure criterion of the energy is implemented by the FISH of the FLAC3O. The mechanical damage is considered for the elastic module decrease due to the energy dissipation. The non-linear computational analysis process can be implemented by the multi-linear elastic model analysis. Finally, numerical results are provided to demonstrate the utility and robustness of the proposed method.
