【Abstract】For the aim of studying the anti-seismic performance of concrete gravity dam under earthquake loads, the Guangzhao concrete gravity dam with 200 meters height in the Southwest China was taken as an example. The three-dimensional finite element model of the dam body–reservoir water–foundation system was established. Dynamic analysis and seismic vulnerability analysis were carried out based on the incremental dynamic analysis (IDA) method. According to the IDA results of the whole dam model, the displacements of the dam crest and the bottom hole were extracted. The IDA curves, the fractile curves, and the seismic vulnerability curves were obtained. It is concluded that when the PGA of the seismic wave was below 0.2 g, the probability of damage to the dam was very low; when the PGA was 0.3 g or less, the basic function guarantee of the dam can be satisfied; when the PGA was below 0.6 g, the basic safety requirement of the dam can be met.
