Abstract: Seismic risk analysis for concrete gravity dams is to discuss the possibility of the dam subjected to a certain level of earthquake in operation period, and the probability of certain earthquake disaster and social consequence during earthquake. The model of seismic risk assessment is founded combined with seismic damage evaluation criteria given by researchers, as well as seismic hazard and seismic fragility analysis. As an engineering application of the method, the risk probabilities of different seismic damage of Jin'anqiao dam are obtained. This research is helpful to optimize seismic design, reinforcement and maintenance measures.

Key words: concrete gravity dam, seismic risk, seismic hazard, seismic fragility
