摘　　要：采用三维有限差分法,对水布垭地下洞室群围岩稳定性进行了分析。通过多种方案计算和比较,论证了局部软岩置换、支护型式优化、支护参数优化的合理性。在此基础上对地下洞室围岩的整体稳定性作出评价。The stability of surrounding rocks of the cavern group for the Shuibuya underground powerhcuse is analyzed by using FLAC-3D .Through comparison of the results of assorted computation schemes, replacement of soft rock mass and optimum selection of anchoring support as well as feasible excavation sequences are illustrated.Finally, the stability of the underground powerhouse is evaluated.

关 键 词：围岩稳定 支护优化 软岩置换 喷锚支护 三维有限差分法
