Abstract Research purposes：The strata of Zhengzhou and its surrounding area along Shijiazhuang-Wuhan Passenger Dedicated Linemainly contain saturated silt, mealy sand and saturated clay, so ground settlementand the crack of soil body around the pile happened during construction. In order to solve these problems, the research was done on application of long spiral pump pressure CFG pile in reinforcing soft soil subgrade to control the ground settlement deformation and improve the construction quality of the line.
Research conclusions：Through the research on the method for application of long spiral pump pressure CFG pile in reinforcing soft soil subgrade, the construction technique, construction flow and the key points forcaution in construction were put forward, the technical problems probably happened in construction were analyzed and the controlmeasures probably to be takenwere given. The practice showed application of thismethod could achieve a good resultand it could be as the reference to the similar works.
