灰土挤密桩在湿陷性黄土路基中的应用与分析

Application and Analysis of Lime-soil Compaction Pile in Collapsible Loess Roadbed

摘要: 湿陷性黄土路基主要特征在于受水浸湿后，自身重力加大，在外部荷载共同作用下，极易发生沉降变形，甚至破坏公路结构。基于此，本文提出了灰土挤密桩法，并在全面了解其作用原理的基础上，结合具体案例，对其施工技术要点进行了分析与探讨。

Abstract: The main feature of collapsible loess subgrade is that after being soaked by water, its own gravity increases. Under the joint action of external load, it is easy to occur settlement deformation and even damage the highway structure. Based on this, the paper puts forward lime soil compaction pile method, and on the basis of comprehensive understanding of its action principle, combined with specifi c cases, analyzes and discusses its construction technology points.
