摘　　要：结合"九五"国家科技攻关项目———沙牌工程,采用考虑参数变异性的基于概率理论的可靠度分析方法———复合形法,计算得出沙牌拱坝上、下游坝面及诱导缝结点的可靠度指标β的分布规律,并进一步分析了坝体设缝后诱导缝及坝体开裂失效的可能性。In connection with one of the national key projects,problems of which were scheduled to be tackled in the state ninth five year plan--Shapai RCC arch dam,the reliability analysis method based on probability theory with variability of parameters in consideration--the complex form methed was used in this paper.The reliability indexes β of Shapai arch dam upstream & downstream faces & inducing joint nodes were calculated with the method.Furthermore,failure probability of the dam inducing joints & body due to cracking was analyzed.
