摘 要

斜坡堤是用来抵御外海来浪对陆域侵袭的重要海岸建筑物。斜坡堤的越浪则影响到斜坡堤的使用安全，因此对斜坡堤的越浪过程的分析显得尤为重要。本论文中使用数值方法分析各种斜坡堤的越浪过程。研究中使用SALOME软件进行建模、选取OpenFOAM模拟斜坡堤的越浪过程，然后使用ParaView执行后处理、数据分析和结果演示。研究中采用五阶斯托克斯波作为入射波，模拟了简单斜坡堤的越浪过程，分析比较了光滑斜坡堤与带栅栏板斜坡堤的越浪过程及其差别，并且对越浪量进行了计算，数值结果和已有文献数据进行对比，验证了不同形式斜坡堤的越浪过程。

Abstract

The slope dike is an important coastal structure used to protect the land from the sea waves. The overtopping on slope dike affects its safety and it is very important to analyze the overtopping process. In this paper, numerical methods are used to analyze the overtopping process of various slope dikes. In present study, SALOME software is used for modeling and OpenFOAM is selected to simulate the overtopping process on slope dikes. ParaView is used for post-processing, data analysis and demonstration of results. The fifth-order stokes wave is set as the incident wave to simulate the overtopping process on a simple mound breakwater. Numerical results for slope dike without and with fence panels are compared. The overtopping discharge is calculated and numerical relevant results are plotted against existing analysis, which has shown the process of overtopping on different forms of slope dikes.

KEY WORDS: numerical simulation; slope dike; overtopping; fence panels
