| Abstract: | Numerical simulation analysis was performed on the excavation process of underground cavern of underground powerhouse based on 3D elastoplastic FEM method, It adopted ANSYS software. On the calculation results, the study was 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, some suggestions for design and construction are given, it should serve as a valuable reference for engineering practice. |
