摘要：

In this paper, a landslide-induced surge wave and its overtopping of a dam is simulated using a coupled ISPH model. In the model, the mirror particle treatment was employed to simulate the moving structures and a particle symmetry criterion was enforced for free surface judgment. A telescopic boundary is presented for the landslide body motion treatment. The model is first used to simulate the two types of surge wave induced by submarine and aerial landslides and the simulation results are compared to the previously published experimental data. Then, in order to study landslide-induced wave propagation and especially the overtopping of a dam, laboratory experiments were conducted in which the landslide motion, the wave gauge results and the total overtopping volume were presented and compared to the numerical results. It was found that the present numerical model can accurately simulate the entire process of surge wave generation, propagation and overtopping of a dam.
