Abstract: The spatial vibration responses of slab track and twin-block track and bögl slab track under high-speed train are calculated on the basis of the spatial vibration models of different type ballastless tracks and the analysis theory of spatial vibration of high-speed train and ballastless track system, respectively. The effect of different type ballastless tracks and speed on the dynamic responses of the system is analyzed and compared. It is shown that the effect of different type ballastless tracks on the vertical rail displacement, vertical slab displacement, vertical slab acceleration, vertical wheel-rail force, derailment factor and wheel load reduction factor, etc. is high, and the effect of different type ballastless tracks on other dynamic responses of the system is very low. Comparatively, the dynamic performance of bögl slab track is better than that of twin-block track, and the performance of slab track is the worst.
