潮流泥沙数值模拟在潍坊港规划中的应用

摘要

To solve the problem of Weifang Harbor general plan, numerical model is used to study comparison of project schemes.MIKE 21 software is applied to set up 2D tidal current and sediment numerical models about the Weifang Harbor sea area.Numerical simulations of current, topography changes and channel siltation are carried out to compare all planning schemes.The results show that current and topography don' t change obviously after each scheme. The channel deposition is the key factor to select the scheme. Unitary schemes are obviously superior to separated ones.The scheme with offshore breakwater is not suggested at present.%将潮流泥沙数学模型应用于潍坊港总体规划方案比选研究.采用MIKE21软件建立潍坊港二维潮流泥沙数学模型,对总体规划的各项方案进行水流、 地形冲淤、 航道回淤等方面的数值计算,并进行方案间的比较分析.研究结果表明,各方案工程实施后流场无明显差别,周边地形冲淤变化不大且差别较小;航道回淤是该区域规划方案选择的关键因素,整体发展方案明显优于分离式方案;经多方面考虑离岸岛堤式方案尚不可行.
