With the increase of train speed, the environmental vibration becomes obvious. The vibration induced by train is transferred to superstructure, and the structural safety and serviceability are affected, which should be settled in design. The vibration responses of terminal of Beijing Daxing International Airport are calculated, the vibration amplitude, distribution and time history characteristic are studied, the vibrations caused by air flow or wheel-track excitation are analyzed separately. The results show that, when train speed is 350km/h, the vibration induced by train air flow is very significant for the non-tunnel structure of Beijing Daxing International Airport, which should be considered in design.
