摘要

作为海上风电机组的常用基础形式

大直径海洋钢管桩基础的桩-土作用模式与传统小直径桩区别明显

常用的美国石油学会API规范无法准确评估大直径海洋钢管桩基础的承载性能。采用数值分析方法研究砂土中不同桩-土刚度比对大直径单桩水平承载特性的影响

揭示了桩-土刚度比和位移选取条件对单桩水平承载力的影响规律

结果表明：随着桩-土刚度比的增大

单桩水平承载力呈现降低趋势

且随着桩径的增大

水平承载力对桩-土刚度比的敏感性减弱;不同泥面位移下单桩水平承载力与桩-土刚度比均呈现对数关系。基于水平承载模式、位移条件和土体强度对水平承载力的影响

建立大直径单桩归一化水平承载力计算方法。

Abstract

As a common foundation type for offshore wind turbines

the pile-soil interaction mechanism of large-diameter marine steel pipe pile foundations is significantly different from that of traditional small-diameter piles. The commonly used API specifications are unable to accurately assess the load-bearing performance of large-diameter marine steel pipe pile foundations. This study employs numerical analysis methods to investigate the influence of different pile-soil stiffness ratios in sandy soils on the horizontal load-bearing characteristics of large-diameter single piles. It reveals the influence laws of pile-soil stiffness ratios and displacement selection conditions on the horizontal load-bearing capacity of single piles. The results indicate that

as the pile-soil stiffness ratio increases

the horizontal load-bearing capacity of single piles tends to decrease. Moreover

with the increase in pile diameter

the sensitivity of the horizontal load-bearing capacity to the pile-soil stiffness ratio weakens. The horizontal load-bearing capacity of single piles exhibits a logarithmic relationship with the pile-soil stiffness ratio under different seabed displacements. Based on the influence of horizontal load-bearing mechanisms

displacement conditions

and soil strength on the horizontal load-bearing capacity

a normalized horizontal load-bearing capacity calculation method for large-diameter single piles is established.
