摘　　要：以中国南海某海上风电吸力筒导管架基础为分析对象,以50 a重现期极端工况为载荷条件,考虑筒-土接触建立全三维有限元模型,对吸力筒导管架的安装角度和结构强度、地基沉降以及筒基承载力进行分析。结果表明,当基础安装方向与浪流作用方向的相对作用角为120°时,基础所受载荷响应最小。地基承载力和基础强度满足要求。在基础及风机安装过程中最大产生0.431 m土体沉降,应为基础预留足够的沉降量。Taken the foundation of the suction bucket jacket of an offshore wind power planted in the South China Sea as the analysis object,and taken the extreme working conditions of the 50-year return period as the load condition,a full three-dimensional finite element model is established considering the contact between the bucket and the soil.The installation angle and structure strength of the suction bucket jacket,foundation settlement and bearing capacity of bucket foundation are analyzed.The results show that when the relative angle between the installation direction of the foundation and the direction of wave action is 120°,the load response of the foundation is the smallest.The foundation bearing capacity and foundation strength meet the requirements.The maximum soil settlement of 0.431 m is generated during the installation of the foundation and wind turbine,so that sufficient settlement should be reserved for the foundation.
