摘　　要：利用MIKE 21 Flow Model_FM HD模块搭建包括莱州湾在内的整个渤海水动力模型,在实测资料验证良好的基础上,对工程建设前后潮流场进行了数值模拟,并就海上风电场工程建设引起的局部潮流场变化进行了分析。结果表明,工程建设前后大范围的涨、落潮流态基本没有变化,工程建设没有改变工程海域的潮流场格局;流速变化主要集中在风电场风机桩基附近。桩基背流面流速减小值大于迎流面流速减小值,迎水面桩基两侧流速均有所增大,但流速增大的范围比流速减小的范围一般为小。In order to study the effects of the offshore wind farm construction in the Laizhou Bay on the local tidal current field,the numerical hydrodynamic model for the Bohai Sea,including the LaizhouBay,was developed with MIKE21Flow Model_FM HD module.The calculated results were compared tothe measured results,and it is found that good agreement was obtained.The calculated tidal current field before and after the project construction was analyzed,and the variations of the local tidal current field around the offshore wind farm were discussed in detail.The results show that,for the Bohai Sea and the Laizhou Bay,the tidal current field pattern of flood and ebb tide in the presence of the project basically correspond to those in the absence of the project,and that the tidal current field in the vicinity of pilefoundations of the wind farm is changed.It is illustrated that the decreased current speed on the front faces of the pile is larger than those on the back faces,that the current speed around the both sides on the front faces of the pile is somewhat increased,and that the range of speed decrease is smaller than the range of speed increase.
