摘要
根据预压桩托换法的工艺特点,通过桩–土相互作用的工作原理分析,得出预压桩托换中桩体回弹的工作机理。结合工程实践,运用线性回归分析得出桩体回弹力与控制回弹率的关系式,给出桩体回弹的控制方法。
According to the technical characteristics of preloading piles, by analyzing the mechanism of interaction of piles and soil, the mechanism of rebound of piles in the course of underpinning was gained. Relationship between the rebound force of piles and the controlled rebound proportion was obtained by using the linear regression analysis, and the controlling method of rebound of piles was given.
