| Research Abstract |
Mechanism of progressive failure of landslide dam during seepage and overtopping was discussed through in-situ tests, model tests and numerical analyses. The results showed the internal structure of landslide dam, external erosion properties of dam material, internal erosion process of dam, stability index of dam during seepage and overtopping.
