Abstract: The sudden sliding of dam body may lead to failure of the landslide dam. In this paper, study of three-dimensional transient seepage and analysis of slope stability of landslide dam are carried out. The three-dimensional slope stability model and transient seepage model are coupled in the numerical simulation, and the water movement measurement and failure surface observation test are carried out in the flume. The predicted results of water distribution at different dam parts and the critical sliding surface are very close to the experimental results.

Key words: seepage, slope stability, 3D model, numerical simulation, laboratory test
