摘要建立以微震监测为主、应力场分析为辅的水工岩质边坡稳定性分析方法。利用RFPA3D分析软件，研究三维条件下锦屏一级水电站左岸岩质边坡破坏过程微破裂的萌生、演化、扩展、相互作用和贯通机制，揭示边坡整体失稳破坏模式，探讨岩质边坡渐进失稳破坏过程应力场和微震活动性空间演化基本规律，形成从细观损伤演化过程揭示宏观岩体结构破坏的研究方法。研究结果表明：断层F5，F2和煌斑岩脉X等软弱结构面是控制左岸边坡破坏模式的关键因素之一，RFPA3D离心加载法得到的边坡潜在滑移面及声发射与微震监测系统得到的岩石微破裂空间宏观演化趋势比较一致。

Abstract：An analytical method for stability analysis of hydraulic rock slope incorporating microseismic monitoring and stress field analysis，was established. The initiation，propagation，extension，interaction and coalescence mechanisms of microcracks during the progressive failure processes of the left bank slope at Jinping I hydropower station were investigated using realistic failure process analysis code in three dimensions(RFPA3D). The whole instability failure mechanism of rock slope was revealed. The spatial evolution regularity of stress field and microseismicity of the rock slope during progressive failure processes were discussed；and research method was thus formed to reveal macroscopic rock mass structures failure from mesoscopic damage evolution processes. The comprehensive researches show that the weak structure planes such as faults F5，F2 and lamprophyre X are one of the key factors controlling the failure modes of the left bank slope. The potential sliding surface and its acoustic emission of the rock slope obtained by RFPA3D are in good agreement with the trend of spatial macro evolution of rockmass microcracks captured by microseismic monitoring system.

Key words： slope engineering Jinping I hydropower station rock slope stability numerical simulation microseismic monitoring
