摘　　要：随着海上风电的深远海和风电机组大型化发展趋势,固定式单桩基础的直径随之增大,现有的理论方法及简化模型已无法准确地指导设计,多分层地基条件下的大直径单桩承载特性亟需科学评估。根据3个风场的五根试桩现场水平承载力试验数据,对有限元模型的参数化输入进行率定,并对水平试桩荷载位移曲线的工程数据进行拟合,推荐有限元模型的砂土弹性模量应取压缩模量的1倍,黏性土取3倍。With the development trend of deep-water offshore wind farms and large-scale wind turbines,the diameter of the fixed monopile foundation increases accordingly.The existing theoretical methods and simplified models cannot guide the engineer design accurately.It is urgent to evaluate the lateral bearing capacity of large diameter monopile under multi-layer foundation.According to the horizontal bearing capacity test data of five test piles in three wind fields,the parametric input of the finite element model is calibrated,and the engineering data of the horizontal test pile load to displacement curve is fitted.It is recommended that the elastic modulus of the finite element model should be 1 times of the compression modulus of the sand and 3 times of the clay.
