本文采用耦合的ISPH模型，模拟了滑坡涌浪及其漫坝。模型中采用镜像粒子处理来模拟运动结构，并采用粒子对称性判据来判断自由表面。提出了伸缩边界处理滑坡体运动的方法。首先利用该模型对海底滑坡和空中滑坡两种类型的涌浪进行了数值模拟，并将模拟结果与已发表的实验数据进行了比较。然后，为了研究滑坡引起的波的传播，特别是漫坝，实验室进行了滑坡运动，波仪的结果和总的越浪量，并与数值计算结果进行了比较。计算结果表明，该数值模型能较准确地模拟涌浪的产生、传播和漫坝的全过程。
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.
