Abstract The high-speed train makes strict demands on the long-term performance of the track-subgrade. The key scientific point of research on the performance of high-speed railway subgrade is the mechanical and hydraulic properties of the subgrade under the coupling of dynamic cycles, dry-wet cycles, and temperature cycles. Much further research work should be done for the maintenance of existing high-speed railways and the new construction of high-speed railways.
