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.
