CFG桩在中业大厦复合地基中的应用

An Application of CFG Pile in Composite Foundation of Middle Industry Building

CFG复合地基是粉煤灰碎石桩、桩间土和褥垫层形成的一个完整整体,上部建筑物的荷载整体上由其承担,这样的复合地基充分利用了桩间土的承载力,而不是像桩基那样利用桩来承担上部荷载。这样的设计思路加上CFG桩不配钢筋,所用粉煤灰价格低廉、易得,大大降低了工程造价。

CFG composite foundation is the fly ash gravel pile and soil between piles and cushion layer to form a complete body.This composite foundation can make full use of the bearing capacity of the soil between piles,rather than the pile foundation pile to bear the loads that use.This design idea plus the CFG pile is not matched with steel.The cost of the fly ash is lowand the cost of the project is greatly reduced.
