摘　　要：曹妃甸港是我国最大规模的围海造地建港工程,建设始于2003年,至今仍处于建设阶段。因此,对曹妃甸海域在不同围垦建设时期的水动力条件变化进行研究很有必要。该文采用Delft 3D软件建立曹妃甸海域三维潮流数学模型,使用实测资料对模型进行验证。运用验证后的模型对曹妃甸工程四个阶段(无工程、2009年工程、2012年工程和预期工程)下的潮流场进行了模拟。在此基础上,探讨了曹妃甸海域的潮流特征、潮流的分层特点和潮流场随着工程建设的变化情况。结果表明,2009年工程建成后,甸头附近的潮流流速增大10%―40%,甸头东部前沿流速总体减小约10%―20%,港池区域和通岛堤附近区域流速则大幅减小,最大减幅约60%。但随着工程的进展,老龙沟和一、二港池区域的流速会有进一步轻微的减小,而其他区域的流速变化不大。Caofeidian harbour is the largest reclamation project to construct a deep water harbor in China. This construction began in 2003 and is still underway. So it has important meaning to study the changes of hydrodynamics at different constructionstages in Caofeidian sea area. A 3D numerical flow model of Caofeidian is established based on Delft 3D. This model is validated with the field data. The validated model is used to simulate flow fields at four stages （no project, 2009 project, 2012 project and the expected project）. On the basis of this verified model, the features of tidal current in Caofeidian sea area, the characteristics of tidal current velocities in different vertical levels and changes in tidal current fields with the development of the project are computed and analyzed. The results show that, after the completion of 2009 project, the tidal current velocities are larger by 10%-40% than that without project near Caofeidian foreland and smaller by 10%-20% in east foreland. The tidal current velocities also decrease by 60% at most near the approach jetty and in basins of Caofeidian harbor. However, with the further development of the project, the tidal current velocities further slightly decrease in Laolonggou deep trough, the first basin and the second basin of Caofeidian harbor, and change slightly in other areas.
