黄骅港工程对其海域流场影响的计算分析

利用Delft3D-Flow数学模型,模拟了黄骅港附近海域不同潮型、不同工程状况下的潮流场,在此基础上,分析比较了黄骅港不同时期工程情况下潮流场的主要变化,探讨了二维流场变化对黄骅港港池和外航道回淤的可能影响.研究表明:工程前后黄骅港海域的流场发生了显著的变化,潮流动力条件发生不均衡变化,出现了沿堤流和横流,这些因素都有可能加重黄骅港港池和外航道的回淤.

Numerical Simulation and Analysis of the Effect of Huanghua Harbour on Tidal Flow

With the application of Delft 3D-Flow model,the tidal current fields are simulated under the varied tidal types and the different engineering conditions.Furthermore,this model is used to study the influence of the harbor engineering on tidal current field and its possible impact on sediment back-siltation in the basin and outer navigation channel of the harbour.The numerical results show that,there is an obvious change of the flow field after the construction of the harbour,the tidal dynamic condition changes unsymmetrically,and the currents along the breakwaters and cross the channel entrance appear.These factors may enhance sediment siltation in the basin and navigation channel of the Huanghua harbour.
