摘要
水泥粉煤灰碎石桩(以下简称CFG桩)在湿陷性黄土、粘性土、粉土、砂土地区已经被应用和推广,但在人工填土和淤泥质粉质粘土中能否应用,工程界尚未统一认识。通过CFG桩在淤泥质粉质粘土层地基处理中的应用,进行变形及地基承载力等参数的设计计算,并在静载试验和沉降计算中进行检验,证明了复合地基设计计算的实用性及施工方法的可行性。
The cement-flyash-gravel pile（CFG pile） is widely used in the collapsible loess, clay soil, silt and sandy soil, whether it is suitable in the artificial filled soil and silty clay isn＇t recognized. Parameters such as deformation and bearing capacity, etc. are designed and calculated after treatment of the silty clay by CFG pile, which is tested by the static load test and settle- ment observation. From the results, it is shown that the design, calculation and construction is feasible.
