A great many large dams with high seism have been built and will be built in the northwest and southwest regions in China. As large dams have great significance for the national economic development, the aseismic safety evaluation of large dams is an important part of earthquake engineering. The aseismic safety assessment criteria of dams based on the probabilistic method has been an important trend in the safety research of hydraulic structure in recent ten Year>s. Based on the gravity dam, the linear elastic mode-superposition response spectrum method is used in the seismic response; the dynamic and static combination method is discussed. The method of seismic dynamic reliability analysis of gravity dam is also established using the stress coefficient method and Monte-Carlo simulation method. The point strength reliability in the dam and the seismic sliding stability reliability can be calculated via this method. It is simple, convenient and efficient.
