摘要：
In order to study vibration and noise problems of the integrated transportation hub under train load excitations, a field experiment was carried out taking the Shapingba station of Chengdu-Chongqing high-speed railway as the engineering background. The vibration accelerations were measured in the station waiting hall, platform and track slab, while the radiated sound pressures were measured in the waiting hall, platform and track area. Then, time-domain analysis and one-third octave analysis were applied to the measured signals, and the vibration transmission law and noise characteristics of the station induced by running trains were studied. According to the test analysis results, under the train running load the dominant vibration frequency band of the station and platform is 10.0-80.0 Hz. The vibration decreases with the increase of distance from the vibration source, and the maximum attenuation of the total vibration acceleration level from the platform to the waiting hall is13.5 dB. The maximum vibration acceleration level of track plate appears at 400.0 Hz, which is about 101.0 dB. The dominant frequency band of the sound pressure level in the waiting hall is 20.0-2 500.0 Hz, and the overall sound pressure level of the train entering station is about 0.5-1.3 dB(A) higher than that of the train leaving. The dominant frequency band of the station noise is 125.0-1 000.0 Hz, and the overall sound pressure level of the station during the outbound period is 87.3 dB(A), which is 1.3 dB(A) higher than that of the inbound period. The dominant frequency band of wheel-rail noise is 200.0-2 500.0 Hz, and the overall sound pressure level of the train entering station is 91.1 dB(A), which is higher than that of the train running outward the station by 3.1 dB(A). © 2020, Editorial Department of Journal of Southwest Jiaotong University.
