| Abstract: | According to analysis of action mechanism of compacted pile and CFG pile,this paper elaborates on the multi-pile composite subgrade technique which compacts the foundation soil first and then constructs the CFG pile.With practical project,design method and construction procedures are described in detail for compacted pile and CFG pile in collapsible loess area.Through the evaluation of composite subgrade detection results,it indicates that the design method has the advantages of cost reduction,construct period shortening and technology advanced.It can be used in collapsible loess area extensively. |
