Abstract
Shaking table test and numerical analysis with dinstinct element method on earth dam were carrid out to establish the perfomance-based design. The numerical analysis could reproduce the results of model tests. In additionally, the resluts from the model tests and numerical analysis showed that the level of damages in earth dams could be expressed by the ratio of the settlement and height at the crest. A criteria related to the damages in earth dams was proposed in this paper.
