摘要
打桩挤土使周围土体发生位移,对周围其他桩及附近原有建筑物和基础设施产生破坏。本文通过典型工程打桩过程中的监测数据,运用小孔扩张理论结合回归分析方法导出了计算土体位移量的经验公式。运用该公式可定量预估挤土程度,防止意外事故的发生。
Pile-driving will cause the surrounding soil deformation, and even may cause damage on surrounded buildings and the ground. An empirical formula is induced by analyzing the in-site testing data during the pile-driving with the theory of small expansion and the method of regression. The formula can be used to predict quantitatively the extent of soil deformation in order to avoid any unexpected accident.
