摘要
统计数据表明,单桩基础在海上风机基础形式中所占比例为65%以上,开展单桩基础设计与分析方法的研究具有重要的工程应用意义。根据海上风电机组基础所处的环境特点和结构特性,介绍了海上风机单桩基础的设计要点。结合某海上风电场风电机组单桩基础设计实例,建立了单桩基础有限元模型,进行了基础承载力与变形计算、模态分析和疲劳分析等工作,给出了相关设计成果,可供相关设计人员参照使用。
Statistical data show that monopile foundation accounts for over 65% of all foundations for offshore wind turbines, so it is of great engineering value to perform the research on the design and analysis of monopile foundation. The design points of monopile foundation for offshore wind turbines are introduced in the light of specific environmental and structural features. Based on an example of designing the monopile foundation for an offshore wind farm, the finite element model for monopile foundation is established in this paper. The calculation of foundation bearing capacity and deformation, as well as modal analysis and fatigue analysis are also conducted, achieving relevant design results, which functions as a reference for designers.
