中文摘要：

该文在FLUENT软件平台上，发展了数值消波-造波技术，通过在动量方程里添加多孔介质源项，建立了带有多孔介质模型的二维数值波浪水槽。应用该数值波浪水槽，数值模拟了在斜坡堤坡面上铺设异形块体情况下的越浪过程，给出了越浪量。为了率定异形块体的等效惯性阻力系数，进行了典型工况的物理模型实验，给出了在斜坡堤坡面上不同位置处铺设一层异形块体情况下多孔介质模型的等效阻力系数。

英文摘要：

The 2D numerical wave flume, based on CFD software FLUENT, is developed to study overtopping over a seawall with dolos, in which the porous media model is used to simulate the energy dissipation effects due to dolos on overtopping. Comparing the numerical results of overtopping with the experimental data, the effective resistant coefficient of porous media mode is determined for the cases of different locations of dolos on the slope of seawall.
