| 摘 要： | 为了对波浪荷载作用下近海风电大直径单桩基础受力变形特性的影响因素进行分析，以江苏省如东县某近海区域的水位地质条件为基础，运用有限元模拟软件 ABAQUS 进行数值模拟，对荷载大小、荷载位置、土体压缩模量、桩体自由度影响因素展开分析。通过影响因素的不同量值，得出近海风电大直径单桩基础动载情况下受力变形特性的变化规律，从而为实际施工提供有价值的参考。

| Abstract: | In order to analyze the influencing factors of the force and deformation characteristics of offshore wind power large-diameter single-pile foundation under wave load, based on the water level geological conditions of an offshore area in Rudong County, Jiangsu Province, the numerical simulation was performed using the finite element simulation software ABAQUS, and developed Analysis of factors affecting load size, load location, soil compressive modulus, and pile degrees of freedom. Based on the different magnitudes of the influencing factors, the change law of the force and deformation characteristics of the offshore wind power large-diameter single-pile foundation under dynamic load conditions is obtained, which provides a valuable reference for actual construction. |
