摘要

运用最小二乘法定量探讨了微型静压桩在托换过程中回弹力与回弹量之间的关系；运用桩-土相互作用机理定性分析了回弹产生的原因，并研究了静压桩桩顶的最大回弹量，同时得到了回弹力、托换力、实际回弹量与最大回弹量四者之间的关系式。

Abstract

The relationship between the rebound force and the rebound value of the underpinning static pressure piles is discussed quantitatively by using least square method. And the reasons of rebound are analyzed quantitatively through the pile-soil interaction mechanism. The maximum rebound value of the static pressure pile-head is also studied. Meanwhile

the relationship among rebound force

underpinning force

actual rebound value and maximum rebound value

is obtained.
