摘　　要：采用二维弹塑性有限元法对金顶水电站工程地下厂房开挖后的围岩稳定性进行分析,得到了开挖后的围岩位移、应力和塑性区分布规律。计算结果表明,地下厂房结构设计合理,围岩变形不大,应力状态良好,地下厂房岩体整体是稳定的。After excavating, the distribution laws of the displacement, stress and plastic zone of surrounding rock of underground powerhouse of Jinding hydropower station are obtained through analyzing the stability of the surrounding rock by 2D elastic-plastic FEM. The results show that the underground powerhouse has reasonable structure design, the surrounding rock has small deformation and good stress state, and the rock mass of the powerhouse is stable onthe whole.
