崇明生态岛海塘达标工程波浪数值模拟研究
|
摘要
为给崇明岛海塘达标工程提供设计波浪要素并深入研究波浪情况,采用MIKE 21模型,考虑实际水底地形、波浪折射、浅化、反射、破碎等条件下,模拟工程区域内的波高分布情况。结果表明:MIKE 21模型可以较好地模拟波浪生成和传播过程,模型在上海崇明地区应用是合适的;分析崇明岛区域波浪的变化分布情况,为海塘达标工程提供波浪要素,并从波浪分布的角度给出建议。
In order to provide the design wave elements and study the wave situation of Chongming Ecological Island Seawall Upgrading Project, and considering the practical conditions of underwater terrain, and wave refraction, shoaling, reflection and breaking, the MIKE 21 model is used to simulate the distribution of wave height in the engineering area. The result shows that MIKE 21 model can better simulate the generating and communicating processes of wave. This model is suitable to use in Chongming District of Shanghai. This paper analyzes the change distribution of wave in the area of Chongming Island in order to provide the wave elements for the seawall upgrading project, and gives the proposals from the viewpoint of wave distribution.
