| Abstract: | Composite foundation with CFG pile and gravel pile is taken in recently deposited liquefying silt ground in Yellow River alluvial plain. CFG pile can increase the bearing capacity of foundation with its rigidity, and gravel pile can eliminate the liquidation of silt ground. This construction method is proved workable. |
