【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。
[Abstract]:Caofeidian Port is the largest reclamation project in China, which began in 2003 and is still in the construction stage. It is necessary to study the variation of hydrodynamic conditions in Caofeidian sea area during different reclamation and construction periods. In this paper, a three-dimensional tidal current mathematical model of Caofeidian sea area is established by using Delft 3D software. The model is validated with measured data. The tidal current field under the four stages of Caofeidian project (no project, 2009 project, 2012 project and expected project) is simulated by using the verified model. The characteristics of tidal current, the stratification of tidal current and the variation of tidal current field with construction in Caofeidian sea area are discussed. The results show that after the completion of the project in 2009, The velocity of tidal current near Diantou increases by 10% and 40 parts, the velocity of velocity in the eastern front of Diantou decreases generally by about 10% to 20, the velocity of velocity in the area of the harbor pool and the area near the island dike decreases substantially, and the maximum decrease is about 60 percent. But with the progress of the project, the old Longgou and one, The velocity of the second port pool area will decrease slightly, but the velocity of the other area will not change much.
