This article uses the developed HSTAR finite element program to simulate the stress state of the dam foundation surface during normal and abnormal operation of a gravity dam, and calculates the relationship between the emptying depth and emptying rate and the anti sliding stability safety factor of the dam foundation surface based on the shear resistance formula in the specifications.\nThe calculation results show that the anti sliding stability safety factor during normal operation meets the regulatory requirements, but for abnormal operation, it is lower than the regulatory requirements during high water level operation, and a dam emptying simulation is required. Based on the simulation results, all expected situations are met.
