| 摘 要： | 外海深水区的波浪传播到近岸浅水区时,受到岛屿、地形与建筑物等影响,发生折射、绕射、反射和破碎等一系列变形。准确计算近岸与港内波浪分布,成为港口与海岸工程研究的重要课题。文章在总结波浪数值模拟发展现状的基础上,对目前常用的基于椭圆型缓坡方程的CGWAVE模型、基于Boussinesq方程的MIKE21-BW模型和基于动谱平衡方程的SWAN模型进行了比较研究。

| Abstract: | When waves propagate into nearshore shallow water from deep water,wave refraction,diffraction,reflection and breaking etc.,may be caused by the island,bathymetry change,coastal structures and so on.It is very important to accurately predict the wave field nearshore or in the harbor for the port and coastal engineering.In this thesis,based on summing up the development of wave models,SWAN model,CGWAVE model and MIKE21-BW model,which are respectively based on the action spectra balance equation,the elliptic m... |
