Firstly, the paper analyzes the concept of soft soil, reasons, engineering properties. Secondly, according to the existing material parameters design embankment, choosing the most unstable transverse stability analysis of the cross. Again, according to the engineering properties of soft soil foundation with sand bags, and CFG pile soft soil foundation treatment for the treatment of these two kinds of design scheme for technical and economic parison, choose CFG pile soft soil foundation. Then, using the method of subgrade delamination summationmethod and stability, and separately calculated, and reduce subsidence of postconstruction settlement measures. Then, the bed surface of roadbed reinforcement and slope protection design, and finally puts forward solutions and deformation monitoring road embankment.
