软土地基上填土对桩的作用问题分析及处理方法探讨

ANAYLYSIS AND REMEDY OF PILES UNDER EMBANKMENT ON SOFT SOIL FOUNDATION

在软土地基上进行填土特别是不对称填土,常常会造成建筑物和构筑物的桩基产生变形或破坏,为了防止此类问题出现,并寻求更好的处理此类问题的方法,结合工程实例对软土地基条件下不对称的填土和开挖时桩基的侧向受力问题进行了分析,对目前此类工程中普遍存在的一些问题进行了探讨,并据此提出了几种保护桩基础的工程措施。对于工业民用建筑和水利工程等的桩基础设计和施工具有一定借鉴参考价值。

Embankment on soft soils, especially unsymmetrical embankment often leads to pile reflection or damage. In order to seek better ways to prevent such problems,an analysis method is presented based on the experience obtained from two of such projects,and some remedy methods are proposed to protect the piles from damage. The presented results may also be helpful to other projects in pile design and construction in hydraulic and civil engineerings.
