| Abstract: | Numerical simulation analysis is performed on the excavation process of underground powerhouse of the hydropower station based on three-dimensional nonlinear finite element method. ANSYS software is adopted including the numerical simulation of excavation, finite element calculation , displacement analysis , Stress analysis, yield area analysis, and the analysis of stability. On the calculation results, the study is focused on the deformation, the stress, the yield area and the integral stability of rock mass and anchor rod on rock bolt crane girder of the underground cavern .The research result provides the basis for the construction of the project. |
