海上风电场桩基基础对水动力特征的影响

Effect of Offshore Wind Farm Pile Foundation on Hydrodynamic Characteristics

以某海上风电场为研究背景,通过等阻水面积方法概化海上风机桩基基础,利用MIKE21 FM模型计算分析桩基基础对水动力特征的影响。结果表明工程后风机基础周围流速发生较明显变化,风机基础背水面流速有所减小,而垂直于涨落及方向流速有所增大;工程海域潮位及流向变化较小。

Based on the research background of a certain offshore wind farm,this paper generalized the pile foundation of offshore wind turbines by means of equal water-resistance area method,calculated and analyzed the effect of pile foundation on hydrodynamic characteristics by using MIKE21 FM model.The results show that the velocity around the pile foundation changes obviously after the project,the flow velocity decreases at the back of pile foundation,but increases in the direction perpendicular to the rising and falling tidal curren.After the project,the change of tidal level and direction of engineering sea area is small.
