| Abstract: | Reinforcing the soft soil foundation with fly ash piles with powders strirred in the deep layer is a question to be tackled by many countries. The mechanism and calculation of the fly ash piles with powders stirred in deep layer are preliminarily studied in this paper by using the methods of X-ray diffraction,EMS (Electron Microscope Scanning),energy spectrum and field tests. It is found that this method can achieve a pile body with strong water stability and a certain strength,the reinforcing result is reliable. At the same time,the average value of the pile side friction drag and the soil strenght coefficient of reduction between piles of the bearing capacity of the composite foundation were obtained. |
