摘　　要：文章在分析南通港吕四港区东灶港作业区一港池通用码头一期工程海域水动力及泥沙运动特点和海床冲淤演变特征的基础上,建立二维潮流数学模型,对工程实施后的流场变化以及港池、泊位的潮流特征进行模拟分析,计算预测工程实施后泥沙回淤情况,为方案优化比选提供技术支持。通过分析得出了工程实施后,港池及码头前沿流速较小,港池内的泥沙回淤强度不大,为工程设计提供了参考。Based on the analysis of the hydrodynamic and sediment movement characteristics and the evolution characteristics of seabed at the No.1 port pool in the Dongzao Port Operation Area of Lvsi Port Area of Nantong Port,A two-dimensional model was established to simulate the engineering area.In this paper,the flow field changes after the implementation and the tidal current characteristics of the harbor basin and berths were simulated and analyzed,also the sediment back-siltation after the implementation of the project was calculated and predicted to provide technical support for the optimization and selection of the scheme.It is concluded that after the implementation of the project,the flow velocity at the front of the harbor basin and wharf is relatively small,and the intensity of sediment back-siltation in the harbor basin is not strong,which provides a reference for the engineering design.
