碎石桩与CFG桩联合处理填土应用

Application of combine gravel pile and CFG pile in filling treatment

结合工程实例,研究了碎石桩联合CFG桩在大面积填土和软弱土处理中的应用技术,对碎石桩、CFG桩、复合地基承载力、压缩模量等进行了设计验算,并对桩基作了检测,指出碎石桩联合CFG桩处理软弱地基是可靠的、合理的,取得了良好的社会经济效益。

Combining with the engineering example,this paper researched the application technology united gravel pile with CFG pile in large ar-ea fill and soft soil treatment,made design and checking to gravel pile,CFG pile,composite foundation bearing capacity,compression modulus etc. ,and detected the pile foundation,pointed out that the gravel pile united CFG pile treatment of soft foundation was reliable,reasonable,a-chieved good social and economic benefits.
