基于非静压方程的斜坡堤越浪数值模拟

摘要

越浪是波浪与建筑物相互作用的一种重要现象，越浪量的大小往往影响到斜坡堤顶高程的设计。为研究斜坡堤越浪问题并对越浪量做出预报，基于非静压波浪数学模型模拟了规则波及不规则波在光滑不可渗斜坡堤上的越浪过程，并分别与小尺度和大尺度水槽的越浪量实验研究成果进行了比较，结果表明基于非静压方程的波浪数学模型能够较好地模拟规则波及不规则波在斜坡堤上的越浪。%The interaction of wave and marine structure produces wave overtopping phenomenon which influences top elevation design of the slope dike usually. In order to investigate wave overtopping the slope dike and forecast the overtopping discharge,non-hydrostatic wave model is built to simulate the overtopping process of smooth and impermeable slope dike under regular and irregular wave. The above overtopping discharge is compared with the experimental data from the flume in large and small sizes respectively,which shows that the overtopping of slope dike under regular and irregular wave can be simulated well with the wave numerical model based on non-hydrostatic equations.
