摘要
综述了水平循环荷载作用下海上风力发电桩基础累积变形的特征及现状,总结了国内外针对海上桩基累积变形的三种常用试验方法:基于p-y曲线的修正法、基于试验的经验拟合法与数值分析方法,并且分析了各类方法的优势与值得商榷的地方,探索实际环境的众多因素对理论的影响,指出该领域的发展趋势是模型统一化、不饱和状态、桩-土等多因素耦合作用下的风电桩累积变形研究,进而利用风电桩的累积变形理论来完善海洋能源工程的设计施工。
This paper presents a review of the characteristics and status of cumulative deformation of offshore wind power pile foundation under lateral cyclic load,and summarizes three commonly used test methods for cumulative deformation of offshore pile foundation at home and abroad:a correction method based on p-y Curves,based on the empirical fitting method and numerical analysis method.This paper also analyzes the advantages and problems of such methods,explores the influence of many factors of the actual environment on the theory and points out that the trend of development in this field is the unification of models,unsaturated state and pile-soil coupling.Then the cumulative deformation theory of wind power pile is used to perfect the design and construction of ocean energy engineering.
