Applied Research Of The CFG Pile In Highway Soft Foundation Treatment

As China’s economy continues to develop, road construction faces increasingly complexgeological environment, China’s vast territory, from the west to the east coast of the LoessPlateau alluvial plain, even the northwest of the desert basins, there exist weak foundation,especially in the eastern coastal economic expansion, investment in infrastructure increasedin the context of how the construction of roads on soft ground in recent years become acommon problem facing the road sector, excessive sedimentation and subsidence betweendifferent structural instability is highway construction on soft ground facing major problems.From the housing construction industry to introduce the CFG pile method can better deal withthese issues, through long practice and theoretical research, you can find CFG pile forquicksand area and muddy areas fixed weak foundation reinforcement effect is very obvious,by using the CFG pile reinforcement on soft ground, making the weak foundation of resilientmodulus meet the basic road effect, to ensure the settlement of soft ground area than roadstandards. Based on this application background, analyzed on a weak foundation oftheoretical calculations using the principle of CFG pile, CFG pile cushion set principles andmethods of operation, CFG pile design methods, CFG pile construction technology andquality control, and finally combined Xing Heng high-speed construction example, the staticexperimental results and theoretical calculations were analyzed over right, right between theaccuracy of the comparison was modified.
