摘　　要：通过对澜沧江某水电站厂房区地下洞室的工程地质条件分析,评价了该电站地下厂房围岩的稳定性。在此基础上,利用三维有限元法对其围岩岩体变形进行分析计算,为洞室位置的选定及支护形式设计提供地质依据。Based on the engineering geological conditions of underground caverns of a hydropower station in Lancang River, the surrounding rock stability of underground powerhouse is evaluated. The deformation of surrounding rock is also calculated by the three-dimensional finite element method. These analyses provide the geological bases to cavern position selection and supporting design.
