摘　　要：利用三维数值模拟方法对连云港区回淤情况进行研究,研究结果表明:港区的泥沙主要来源于近岸浅滩泥沙,在风浪潮流共同作用下泥沙悬扬、搬移,悬沙沿程逐渐落淤,造成港池航道淤积,港内淤积呈现口门处最大、口门内淤积厚度逐渐减小的分布趋势。通过数学模型计算,确定了旗台、庙岭及墟沟港区的月淤积强度;另外,大风或台风天气情况下,港区的淤积会加重,可参照研究结果对各港区回淤强度进行修订。The siltation in Lianyungang port was studied by the three-dimensional numerical simulation technique.The results show that:The sediment in the port mainly comes from the silt of the nearshore and shoals.Under the combined action of wind,wave and currents,the sediment is suspended and transported,and the suspended sediment gradually siltes along the channel,and the position of maximum sediment thickness point at the entrance.Through the mathematical model calculation,the monthly silting strength of Qitai,Miaoling and Xugou port was determined.In addition,the silt would be aggravated by the wind or typhoon weather conditions,and the sediment thickness of each port could be revised according to the results of the study.
