摘　　要：针对在海上风电中应用最为广泛的单桩基础,基于山东、江苏、浙江等地海上风电场的冲刷实测数据,对海上风电场的冲刷深度分布情况进行讨论。同时,运用Qi&Gao公式、韩海骞公式、王汝凯公式对各风电场的理论冲刷深度进行计算,并分析计算结果与实测数据之间的关系,研究各冲刷计算方法的适应性。结果表明,上述3种计算方法可在一定程度上预测单桩基础的局部冲刷深度。For the most widely used monopile foundation in offshore wind power,the scour depth distribution of offshore wind farms is discussed based on the measured data of offshore wind farms in Shandong,Jiangsu,Zhejiang and other places.At the same time,the theoretical scour depth of each wind farm is calculated by using Qi&Gao formula,Han Haiqian formula and Wang Rukai formula,and the relationship between the calculated results and the measured data is analyzed to study the adaptability of each scour calculation method.The results show that the above three calculation methods can predict the local erosion depth of monopile foundation to a certain extent.
