【摘要】：基于Delft3D数值模拟软件建立渤海湾西南岸二维潮流、波浪和泥沙输运数学模型.运用验证合理的模型研究近20年的港口工程建设对渤海湾西南岸水沙动力特征的累积影响以及黄骅、滨州两港水沙动力的相互作用.结果表明,港口工程建设使渤海湾西南岸逐渐形成3个相对独立的海区;波流耦合作用下,全潮平均含沙量分布情况基本与纯潮流时相似,但量值提高近8倍.沿岸流的增强使含沙量等值线趋于与岸线平行,涨潮输沙量的增加使黄骅港以西,黄骅、滨州两港之间以及滨州港以东近岸区域的泥沙含量比例重新分配;总体看来,连片港口工程建设使渤海湾西南岸逐步达到新的输沙平衡状态.黄骅港综合港区与滨州港防波堤一期工程(2012年)与规划工程(2020年)可分别削弱正常天气、常浪天气下港区间泥沙相互输运的影响.
[Abstract]:Delft3D numerical simulation software to establish the southwest coast of the Bohai Bay based on two-dimensional tidal current, wave and sediment transport mathematical model. Using the cumulative effects of port engineering construction model to study the reasonable nearly 20 years on the southwest coast of the Bohai Bay hydrodynamic characteristics as well as Huanghua, Binzhou port two interaction of water and sediment power. The results show that the port engineering the construction of the southwest coast of the Bohai Bay has gradually formed 3 relatively independent area; wave current coupling effect, similar to the whole tidal average sediment concentration distribution and the pure trend, but the value increased by nearly 8 times. The enhanced sediment contour tends to be parallel with coastline coastal current, increase the sediment. Huanghua west of Hong Kong, Huanghua, two between Binzhou port and Binzhou port east of the coastal sediment concentration ratio redistribution; overall, contiguous port engineering construction to the southwest coast of the Bohai Bay gradually reached the new transport sediment The Huanghua port comprehensive port area and the Binzhou port breakwater phase I Project (2012) and the planning project (2020) can weaken the normal weather and the influence of sediment transport in the port area.
