Then they can make the site available to bear the building. But common pile foundation usually ignores the effect from the solid, and the reactive force arrives at 20%~30% of the load of the building in this case. If we don’t consider that case, it might result in waste. In some place, the solid condition is very good. If we process the solid in the site with the solid condition, we will make the foundation available and will save lots of money. Now we list some instance analysis which used CFG pile.Keywords: CFG; reinforce
