Abstract：Research purposes :The research is done on the characteristics of ground vibration induced by viaduct track system.
Research conclusions: (1)The results show the group response relates to the characteristics of frequency dispersion under the effects of point load, that is the low frequency vibration wave is attenuated mare slowly than high frequency vibration wave and when the vibration frequency is close to the main ground frequency, the ground vibration becomes large. (2)In numerical calculation, Rayleigh damping can simulate the ground damping characteristics well and its parameters can be decided with calculation.
