徐圩港区泥沙回淤分析研究

Research on sediment siltation in Xuwei port area

文章应用波浪与潮流共同作用下的大范围泥沙数值模型,模拟计算了连云港港徐圩港区防波堤不同布置方案的泥沙回淤情况,并对计算结果进行了归纳总结。认为口门位置、港区布置形式、无用水域面积是影响港区回淤的主要影响因素。在进行港区布置时,为了达到防淤减淤的目的,应尽量将口门向外海延伸,采取措施阻止含沙较高水流直接到达港池,以及减少港区无用水域面积等。

In this paper,a sediment numerical model considering the joint action of wave and tidal current was applied to simulate the sediment siltation for the different layouts of breakwater in Xuwei port.According to the results,it is summarized that the sediment deposition in the port area depends mainly on the location of the port entrance,the layout of port area,and the useless waterside area in port.To reduce the sediment deposition,the entrance of port should be placed as far as possible in deep water area,the current with the high concentration of suspended sediment should be prevented to flow directly to the waterside area,and the useless waterside area port should be reduced.
