Abstract: The ground motion of pulse type near fault has the characteristics of higher frequency, faster speed and more concentrated energy than that of a distant site, which has serious harm to engineering structures. With abundant water resources, frequent and high-intensity earthquakes occur in Western China, and many high dams are located near fault zones. The permanent deformation and slope safety of high dams under near-fault ground motion are very important. A random pulse ground motion model is established based on the pulse ground motion records of the Jiji near fault in Taiwan Province. Finite element analysis is carried out on the Gushui 250 m grade engineering panel dam, and stochastic dynamic analysis and reliability analysis are carried out on the displacement and slope slip of the high earth-rock dam by the direct probability integral method. The results show that pulse ground motion significantly affects on the vertical deformation and slope stability of high earth-rock dams. The seismic safety and seismic capability of high earth-rock dams near faults with high seismic risk are evaluated comprehensively.
