摘　　要：以混凝土弧线段为过渡段的宽浅式筒型基础所受的波浪荷载较大,易对整个海上风电结构体系的振动响应产生影响。针对某海上风电筒型基础结构,文章基于现场实测数据构建了整机有限元模型,通过数值模拟方法分析波浪荷载对海上风电筒型基础结构塔筒顶部振动响应的影响。结果表明:在风机运行过程中,由风荷载所引起的塔筒顶部的振动响应较波浪荷载所引起的响应要大;在浪高较小工况下,相较风荷载,波浪荷载的影响可以忽略;波浪荷载对风机塔筒顶部振动响应的影响随着外界风速及浪高的增大而增大,其对塔筒顶部振动位移响应的影响比振动加速度大。The wide shallow bucket foundation with concrete arc transition section is subjected to significantly larger wave loads which will easily affect the vibration response of the entire structural system.For an offshore wind turbine(OWT) supported by bucket foundation,a finite element model of the whole wind turbine was established based on the measured vibration data,and then the influence of wave loads on the vibration response of the tower top of the OWT supported by bucket foundation was simultaneously analyzed through the established finite element model.It is shown in the analysis results that the vibration response of the tower top caused by wind load is greater than that caused by wave load during the operation period.Subsequently,the influence of the wave load can be ignored compared to the wind load when the wave height is small.In addition,the impact of wave loads on the vibration response of the tower top increases with the increase of external wind speed and wave height and the corresponding impact on the vibration displacement response of the tower top is greater than the vibration acceleration.
