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

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.
