Abstract:
One of the most important aspects in the stability of arch dams which have been encountered, are the stability of the abutment. In order to assess the stability of wedge, Londe Method has been considered by simple assumption. Displacement and velocity of the wedge were calculated by Newmark beta method. In this study stability of abutment of Luzzone dam due to static and seismic loading was investigated. After modeling a finite element of dam-foundation-reservoir of Luzzone dam, the horizontal and vertical earthquake was applied to the model and the thrust force was recorded. By using a software stability safety factor of wedge was studied.it was found that the wedge is unstable and will move
