| Abstract: | 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. |
