Study of Earth structures stability against earthquake, like embankments, Rock Slopes, retaining Walls and etc, is very important. fu this paper the seismic slope stability of Sardashtspillway was analyzed by using the Log-spiral Upper bound and limit equilibrium methods. The methods presented are based on the rigid block displacement teclmique. fu this note Yield acceleration are calculated for uniform slopes, and irreversible displacements arecalculated for different earthquake records. Due to the obtained results, it was observed that maximum permanent displacement is related to the approach wall near spillway entrance channel in MCE seismic level and Fifth height levels.
