摘要

桩基工程中桩侧负摩阻力所产生的作用于桩体上的下拽力

可能引起桩体破坏、桩基不均匀沉降等诸多工程灾害。为此

工程师们建立了许多单桩负摩阻力计算公式

但是由于这些公式各自的适用性和局限性

计算结果差别较大。首先介绍了目前国内外用于计算单桩负摩阻力及确定中性点位置的几种常用方法:极限分析法、荷载传递法、弹性或弹塑性理论法、剪切位移法和数值分析法;再结合具体工程实例

对以上几种方法进行比较

指出各自的适用条件、优缺点等

为工程设计提供参考。

Abstract

The dragload

which caused by negative skin friction on pile side

may lead to many engineering disasters

such as pile failure

uneven settlement

etc.Although several methods have been established to study the negative skin friction of single pile

they have different occasions for application

and the deduced results from them may differ greatly.Firstly

the usual methods are summarized

such as limit analysis method

load transfer method

elastic or elastic-plastic theory method

shear displacement method and numerical analysis method.Secondly

two case studies are used to appraise the methods

which offer important reference to engineering design.
