摘　　要：在混凝土重力坝尤其是碾压混凝土坝中,混凝土为成层结构,因而层面特性对混凝土坝的安全至关重要,个别坝段水平薄弱面的存在对混凝土坝的整体安全性有重要影响。以可靠度随机有限元法探讨在存在水平薄弱层面情况下碾压混凝土重力坝的安全性,对工程施工及安全控制具有一定的理论与实践意义。The concrete in concrete gravity dam, especially in RCC dam, is a stratified structure, so that its stratification feature is key to the safety of concrete dam. Some times a weak plane will be exist, which will bring important impact to the integral safety of concrete dam. In this paper, the reliability stochastic finite element method is applied to analyze the safety of RCC dam with horizontal weak plane, which has some theoretical and practical significance for the engineering construction and safety control.
