Research on Design Scheme of Lime-soil Compaction pile in Collapsible Loess Regions
The orthogonal experiment method is used to study the influence factors and acceptance indexes of lime-soil compaction piles on foundation treatment in the northwest collapsible loess area.The influences of pile diameter,pile spacing,lime soil content,compaction energy level on the control index of final acceptance project are described in detail.The quantitative effects of the influencing factors including lime soil content,pile diameter,pile spacing and ash compaction energy on the soil compaction degree between piles,composite foundation bearing capacity and Rayleigh wave test results are systematically studied.The conclusions in combination with the actual situation give the specific parameter indexes and guidelines of lime-soil compaction pile method for corresponding specific projects,which provide the systematic theoretical support for corresponding types of projects in future.
