Directed against the practice actuality of deep jet cement in different soft areas, the paper selects two typical soils --mud soil and saturated loess in northwest China, through FEM analysis and in-situ test, compares the stress property of the composite ground formed by deep jet cement pile in different areas. The calculated and in-situ test results as follow: first, the stress ratio of end-bearing pile composite ground is bigger than that of floating pile composite ground; second, the stress ratio in the saturated loess composite ground is bigger than that in the mud soil composite ground when they have same replacement ratio and load; third, the failure mode of the composite ground under the flexible foundation is resulted by the failure of the soil in the ground and this is different from the composite ground under the rigid foundation.
