摘要
探讨了利用工业废渣粉煤炭加固软土的机理，认为利用粉煤灰粉喷桩加固软土地基可以获得很强的水稳性和一定强度的桩体，其加固效果是可靠的.同时依据现场试验对粉煤灰粉喷桩的特性及设计计算进行了初步研究，得出粉煤灰粉喷桩侧摩阻力平均值和粉煤灰粉喷桩复合地基承载力桩间土强度折减系数.
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.
