摘要：
Field measurement was carried out at Nanchang West Station, a large-scale comprehensive transportation hub station. The vibration propagation laws and frequency distribution characteristics of train operation load on Metro Line 2 were studied, and the local vibration laws and spectrum response laws of station structures in comprehensive transportation hub station were analyzed. Research results show that under the action of the operation load of subway trains, the vibration response of the station structure decreases exponentially with the increase of the height of vibration source. The vibration characteristics of different structural floor slabs are different from the main frequency of vibration. As the height from the vibration source increases, the vibration response of the floor caused by the train entering and leaving the station is gradually shifted from high frequency to low frequency, and the attenuation of vibration response is the slowest near the frequency of 60 Hz. In the low frequency range of 5~40 Hz, the vibration response of the transfer floor and the waiting hall floor is greater than that of platform floor. The floor slabs of different spans have different frequency response characteristics, and the larger the span of the floor slab, the more flexible the structure. The propagation distance of the vibration response in the floor area of waiting hall increases by 12 m, and the vibration acceleration level is attenuated by an average of 2~4 dB. The vibration amplification area appears in the area 30~48 m away from the center line of the track. The vibration amplification response has a great influence on the axis. © 2019, Editorial Department of China Railway Science. All right reserved.
