摘要
以中国近海风机承载力研究为背景,采用理论分析结合数值模拟的研究手段,利用大型通用有限元软件COMSOL,建立了大直径海上风电单桩基础与海床的计算模型,进行了水平荷载作用下大直径海上风电桩基础水平承载力的数值计算,分析了水平荷载、桩径等参数对海上风电单桩基础水平位移和桩身弯矩的影响,研究结果可供类似工程参考。
Based on the research of bearing capacity of offshore wind turbine in China,this paper established the calculation model of large-diameter offshore wind turbine foundation and seabed through theoretical analysis and numerical simulation by using the large-scale general finite element software COMSOL.Through this model,the lateral bearing capacity of large-diameter offshore wind turbine pile foundation under lateral loading was calculated,the influence of lateral loading,pile diameter and other parameters on lateral displacement and pile bending moment of offshore wind turbine pile foundation was analyzed,and the results can be used for similar projects.
