摘　　要：使用ANSYS有限元分析软件中的Prob Design模块,利用结构可靠度中比较精确的蒙特卡罗法模拟1000次,对龙滩碾压混凝土重力坝坝基抗滑稳定进行分析,得出可靠指标大于3.7,与规范相比,符合要求,说明该方法计算可靠指标的可行性。The Prob Design module of the ANSYS finite element analysis software was used and the monte carlo method that was considered more accurate in the structural reliability to simulate 1000 times, to analyze Longtan RCC gravity dam foundation anti - sliding stability and reliability, and get reliable indicators that is 3.7 less than norms. This method shows the feasibility of calculating the reliable indicators.
