Static and quasi-static analysis of soil dams in different stages of construction and operation is of great importance. In this research, the stability of the Ilam dam roof during the staged and quasi-static stages in horizontal earthquake accelerations of 0.1, 0.12, 0.13, 0.14, 0.15 The gravity acceleration of the earth is investigated using the slope / w software. Comparison of the results of the model with the standard of the US Army Group of Engineers confirms the stability of the gullies in two static and quasi-static states of the Ilam dam. Rapid drainage of the reservoir has a small effect on the slope stability of the dam. The results of this analysis show that low permeability nuclei are well protected against leaked water into the dam, so that the flow inside the core decreases sharply. Therefore, the slope of the bottom of the earth's dam is always dry.
