打桩引起土体位移的计算分析

Calculation and Analysis of Soil Displacement during Pile Driving

以小孔扩张挤土理论为出发点 ,将打桩问题简化为半无限体中的孔洞问题 ,利用边界单元法 ,对群桩施工过程中引起土体位移进行计算。同时考虑桩施工中控制位移的常用措施 ,并对其效果进行分析计算 。

Process of piles into soil is regarded as hole problem in half infinte body. The displacement of soil produced during piles driving is calculated by boundary element methods. In the meantime, the methods to control displacement are considered.
