摘要
单桩基础是海上风电场的一种重要基础形式。海上风电场单桩基础首先需要承担上部结构传递的竖向荷载,然后还需要承受波浪、海流、地震等作用下的水平荷载,而既有竖向荷载对单桩的水平承载特性会产生重要影响。本文阐述了既有竖向荷载对单桩水平承载特性影响的研究进展。通过对比不同学者的研究成果,分析了既有竖向荷载对单桩水平承载力特性的影响规律、影响原因及影响因素。针对目前国内外学者对该问题研究的不足,提出了若干思考和展望,认为有必要进行影响因素分析和水平循环荷载影响的探究。
The single pile foundation is one of the most important basic forms of offshore wind farm. Firstly, the single pile foundation of offshore wind farm should bear the vertical load delivered from the up- per structure, then it needs to bear the horizontal load generated by wave, ocean current, earthquake and so on. However, the horizontal bearing characteristics of single pile can be influenced by existing vertical load. In this paper, recent advance of existing vertical load＇s effect on horizontal bearing capacity of single pile is presented. By comparing the research results of different scholars, the influence rule, influencing reasons and influencing factors of verti-cal load to horizontal bearing capacity of single pile are analysed. In view of the shortcoming of the research problems, some thoughts and prospects are put forward. It is nec- essary to do the research on analysis of the influencing factors and the influence of the horizontal cyclic load.
