| Abstract: | CFG （Cement Fly-ash Gravel） pile is consisted of rubble, stone, sand, fly ash mixed with ce- ment and water. In sand, silt, clay, silt soil and miscellaneous fill foundation, there have been many appli- cations of CFG technology. The application of CFG pile and matters needing attention in treatment of soft soil foundation of expressway are analyzed in this paper, which can provide reference for relevant con- struction. |
