| Abstract: | 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. |
