摘要
挤土桩为软土地区水工建筑物常用的地基处理方式之一,但挤土桩在高饱和度淤泥软土地基使用时也存在着影响桩基性能的缺点,为减弱缺点的负面影响,基于挤土桩成桩过程对软土物理力学特征的影响机理,介绍一种通过利用桩体的侧向挤压效应使地基软土排水固结,从而提高挤土桩桩基性能的技术创新方法,为类似工程提供借鉴。
Compaction pile is one of the common foundation treatment methods for hydraulic structures in soft soil area,but it also has some disadvantages when it is used in soft soil foundation of high saturation silt.In order to reduce negative effect of shortcomings,based on the influence of compaction pile on the characteristics of soft soil.This paper introduces a method to improve the characteristics of compaction pile foundation by using the lateral compression effect of pile body to make the soft soil drainage and consolidation,so as to provide reference for other projects.
