| 摘 要： | 为了解决三维安全系数在现有的重力坝设计规范中无法参照的问题,利用基于塑性极限分析理论的三维边坡稳定分析方法对重力坝抗滑稳定的安全系数进行了求解,并且采用Rosenbleuth法计算求解了可靠度指标,从而对重力坝深层抗滑稳定的可靠性进行了研究分析。算例和工程实例表明,通过可靠度指标可以对三维边坡的稳定性从失效概率方面加以解释说明。

| Abstract: | To apply the safety factor of three-dimensional slope stability into the design of gravity dams,the reliability of deep slide was studied.The reliability index was calculated using the Rosenbleuth method,where the safety factor was obtained by use of the three-dimensional limit analysis method of slope stability.It was indicated that the three-dimensional slope stability could be explained by the failure probability through the reliability index. |

| Keywords: | slide stability of gravity dam three-dimensional slope stability reliability |
