%X In order to enlarge the usage extent of base materials of rapid transit railway foundation, the dynamic triaxial test is made on cement-improved soil. The dynamic performance of cement- improved soil under repeated load of train is analyzed. The variation and influence factors of critical dynamic stress, accumulated plastic deformation, elastic deformation and resilient module of cement-improved soil are studied. It can be concluded that the dynamic performance of cement-improved soil meets the design demand of rapid transit railway subgrade.
