Abstract:
Seepage in earth fill dams is one of the important factors that may cause the erosion and slope stability if it is ignored, so it is crucial to calculate the leakage discharge through the body of dam and foundation, to avoid economic and life losses. In this research, the seepage analysis of body and the stability of upstream and downstream slopes of Golfaraj dam after construction, stable seepage, rapid discharge of reservoir and OBE,MCE earthquakes have been accomplished and compared applying different limit state equilibrium including: Spencer, Bishop, Johnber, Morgenstern-Price, built-in Geo studio software. The results show that seepage discharge in a deep section without dike is 18.144 m3/day which is reduced in the case of applying a dike or a concrete blanket by 95 and 30.20 percent, respectively. Data obtained from the slope analysis indicate that the slope is stable under any circumstances and the limit equilibrium methods are convergent
