摘要
近年来,国内海上风电发展迅猛,基础多为高耸基础,其中大直径单桩基础是近年来最常用的一种典型基础型式.挤密砂桩作为一种常规软土地基处理方法,国内研究多集中于软土地基加固和复合地基承载力方面,针对大直径单桩桩基转角控制的研究较少,本文结合工程实例,研究了挤密砂桩对桩基泥面处转角的控制影响.结果表明,挤密砂桩可以有效解决桩基泥面处的转角问题,该方法实施经济高效、对后续工程具有指导意义.
In recent years,domestic offshore wind power has been developing rapidly,the foundation is mostly high-rise structure,large-diameter monopile is the most commonly used typical foundation type.Sand pile is a conventional method of soft soil foundation treatment,the research on soft soil foundation reinforcement and bearing capacity of composite foundation are mostly focused in domestic,the study of corner control of large diameter monopile is more less.In this paper,the influence of sand compaction pile on the corner control of the pile foundation is studied.Combined with engineering example,it is concluded that the corner control of the pile foundation at the mud surface is solved effectively,the method is economical and efficient,and has guiding significance for subsequent projects.
