| 摘 要： | 管桩加固软土路基作为一种新的处理方式可以有效地解决路基稳定和总沉降的问题,但是桩顶平面会产生较大的桩土相对位移。对桩土相对位移的形成机理进行分析,利用桩土相对位移的原型观测试验,从变形的角度研究桩土协同工作性状,同时提出了桩土相对位移的控制方法。

| Abstract: | As a new type of soft soil foundation treatment, the roadbed reinforced by prestressed tubular piles can solve problems of roadbed stability and total settlement. But pile-soil relative displacements will appear on pile top plane. The forming mechanism of pile-soil relative displacements is analyzed.The pile-soil coordination rules at the point of deformation are discovered by pile-soil relative displacement prototype observation tests and some measures to control the pile-soil relative displacement put forward. |
