Abstract: On the basis of studying structural system reliability, four failure modes including sliding of the deep dam foundations with weak intercalary strata are considered firstly, the method of the systemreliability of gravity damis inquired. A damexample is set and analyzed, problems needed to research in the future are put forward.

摘要: 在结构系统可靠度的基础上, 首次考虑了重力坝坝趾压坏、坝踵拉裂、沿建基面滑动和沿软弱夹层的坝基深层滑动四种主要失效模式在内的重力坝系统可靠度, 并就其方法进行了探讨。结合实例分析了重力坝系统可靠度, 并提出了方法和今后要做的一些工作。
