As composite foundation with multi?element pile,the under?rammed bored pile,which composites the cast?in?place pile in upper part and the rammed bulb pile in under part,is used in an engineering by combining with the rammed and compacted lime?waste?soil pile.

Combined with project example,it describes the general situation and reinforcement mechanics of the dual compound foundation composed by crushed stone pile and CFG pile simply,introduces the application condition of the compound foundation by the dual piles in the liquefied foundation,and does economic analysis.
