摘　　要：在保证精度的条件下为提高计算效率,在对拱坝进行静力分析的基础上,将结构可靠度的二次响应面法与蒙特卡洛法结合应用于结构的安全计算,对云龙河拱坝进行了可靠度分析。用形式结构相对简单的显式二次函数面的响应来代替复杂拱坝结构的响应,对响应面函数抽样计算代替对大型的三维拱坝有限元模型抽样计算。在保证求解精度的同时也大大缩短了求解时间。To improve the efficiency of the computation under the condition of ensuring the accuracy,based on the static analysis of arch dam,the structural reliability of quadratic response surface method and the Monte Carlo method were combined to be applied to the reliability analysis of the structure,the reliability of Yunlonghe River arch dam was analyzed. The relatively simple structure explicit quadratic function surface response was used instead of the response of the complicated structure of arch dam. The sampling calculation of the response surface function was taken the place of the large arch dam by three dimensional finite element model sampling calculation.Ensured the accuracy of the solution and the time cost had been greatly cut.
