英文摘要：
The state-of-the-art developments on seismic safety evaluation of high concrete dams is reviewed,including：large-scale numerical simulation of seismic ground motion from source-media to dam canyons; nonlinear earthquake damage-cracking behavior of dam-reservoir-foundation systems; dynamic exper imental tests and meso-scale simulation of concrete; and performance-based seismic safety risk evaluation of concrete dams. At the end,the development trends of earthquake-resistant of high concrete dams are concluded.
