摘要
采用三维弹塑性有限元法对某水电站地下厂房主洞室施工开挖过程进行数值模拟计算。通过分析地下洞室开挖过程中围岩和岩锚吊车梁的变形状态、应力状态、屈服区分布以及整体稳定性,得到应力及变形的发展规律以及屈服区出现的部位,指出在设计、施工中的注意事项,为工程设计和施工决策提供理论参考依据。
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.
