摘要：Subgrade settlement at the Sujiatun section of Hada high-speed railway was simulated using the finite element software ADINA, and it was concluded that the subgrade settlement did not meet the specification if the CFG (cement fly-ash grave) piles were not applied to subgrade. By changing the parameters of CFG piles, including cushion modulus, cushion thickness, the diameter and length of piles, and spacing of piles, the relationship between the parameters and subgrade settlement was investigated, with the settlement values obtained on conditions of different parameter combinations. The result shows that the subsidence value is minimal when the cushion thickness is 350 mm, cushion modulus is 120 MPa, pile spacing is 2 m, and the diameter and length of the pile are 0.5 m and 9.5 m, respectively.
