摘　　要：依托莆田某海上风电场项目,以实际单桩机位为例,针对超大直径单桩基础,基于大型有限元软件ABAQUS开展相关的数值模拟计算与分析。通过对影响桩体泥面位移的关键参数进行敏感性分析,探讨土体本构模型、物理力学参数选取以及桩-土接触模型设置等对于基础泥面水平位移计算结果的影响规律。The deformation of the super-large diameter mono-pile foundation of the wind turbines in an offshore wind farm in Putian is analyzed with ABAQUS software.Sensitivity analyses are carried out on key parameters affecting the pile-soil interface displacements.Influences of the soil constitutive model,physical and mechanical parameters,and the pile-soil contact model on the horizontal pile-soil interface displacement of the foundation are discussed.
