摘　　要：采用三维地质力学模型运用超载与强度储备相结合的研究方法进行了坝基稳定破坏试验 ,获得了坝基失稳破坏过程、破坏形态和破坏机理 ,经分析得到两个坝段的综合稳定安全度K为 3.3。同时提出了对坝基相应部位进行灌浆和提高灌浆质量以及对下游蚀变带和F6断层加深混凝土塞等加固处理建议。In this article three dimensional geomechanical model is used to study the dam base stability of gravity dam. And overload and strength reserve are jointly used in the test. The test demonstrated the failure process, failure condition and failure mechanism of the dam base. At last the degree of safety of the whole two monoliths is obtained as 3.3. The opinions of reinforcing treatment with grouting,and deepened concrete plugs to the ecliptic belt of backward position and the F 6 faultage and so on, are suggested then.
