Some subgrade of high-speed railway in operation occurred abnormal settlement,so need to reinforcement, however, the reinforcement measures and these mechanism have got little attention. Numerical analysis method was adopted to study the mechanism and effects of the grounting and churning pile which was used to reinforce soft soil subgrade a high-speed railway Results shows that the settlement and lateral deformation not symmetrical distribution but got larger along the inclined derection of stratum, reinforcement by grouting can decrease the settlement and the transverse differential deformation by improving the properties of soil, which can decrease the viod ratio and increase the compression modulus; reinforcement by churning pile which can increase the stability of embankment on soft soil subgrade. The result could provide theoretical guidance for reinforcement of soft soil subgrade of high speed railway in operation.
