摘要 选取适合的波浪理论是计算海上风电场动力响应的关键,关系到工程设计的成败。基于各种波浪力理论的适用范围,结合东海大桥海上风电场实测水文资料,比较了各波浪理论下波长与水深、波长与波高的关系、在同一周期内的速度变化、加速度变化以及波浪力变化,最终选用Stokes五阶波。最后针对东海大桥海上风电场的基础和水文资料,比较了直、斜桩上的波浪力以及潮流对波浪力的影响。 It’s very critical to select the appropriate wave theory for the dynamic response of wind power at sea,and it even relates to the success or failure of the project.Based on applications of various wave theories and combined with the measured data of hydrology of the wind power form near East Sea Bridge,the results of the relationship among wave length,water depth and wave height as well as the variations of velocity,acceleration and wave force in the same period are analyzed.The fifth order Stokes waves are selected after the comparison.According to the measuring data of hydrology and foundation parameters of the wind power form near East Sea Bridge,the wave forces exerting on the straight and inclined piles are compared,and the effect on the wave force of the tidal currents is analyzed.
