摘　　要：从构皮滩拱坝结构的极限状态出发推导随机有限元方程,进而编制程序,通过有限元程序分别对水位、渗流、温度、构造裂隙、基岩的弹模变化等对拱坝可靠度进行计算,从而找出对该拱坝可靠度影响的敏感因素。Based on the limit state of structure of Goupitan Arch Dam, stochastic finite element equations are derived and then programmed. By using the FEM program, the reliability Goupitan of Arch Dam is calculated with the changes of the factors such as the water level, seepage, temperature, tectonic fissures and the elastic modulus of the foundation rock, and then the more sensitive factors to the reliability of arch dam are found out.

关 键 词：构皮滩拱坝 可靠度 有限元 敏感性分析
