Combination of Gravel Pile and CFG Pile in Dealing with Liquefied Foundation

The gravel pile and the pile of CFG are described about their common characteristics and mechanism. At the same time engineering practice show that the combination of composite founda-tion in dealing with liquefaction can give full play to the gravel pile and the pile of CFG respec-tively. It will achieve both elimination of liquid to a greater extent and improving the bearing capac-ity of the foundation. It is a safe,reliable and economical composite foundation for the liquefied foundation with higher requirements.
