In order to study the vibration characteristics of subway stations caused by subway entry and exit, a three-line parallel transfer subway station in a domestic city was taken as the research object, and the vibration characteristics and propagation rules of the station were analyzed based on the field measurement data. The analysis results show that, affected by the completion and operation of the line, the vibration response of each platform in the station is quite different. Under the inbound condition, the average Z-vibration level of platform 1, platform 2 and platform C is 81.9, 91.4 and 61.7 dB, and the main frequency band of platform 1 and platform 2 is 75~125 Hz. Under outbound conditions, the average Z vibration levels of the three platforms are: 82.7, 93.8 and 63.7 dB, the main frequency band of vibration of platforms 1 and 2 is 50~100 Hz, while the vibration response of platform C is concentrated within 50~60 Hz under both conditions. It can be found in most measuring points in the station that the vibration under outbound conditions is greater than that under inbound conditions, and the maximum difference is about 2.5dB. After the vehicle-induced vibration is transmitted to the ground floor, it will first produce a certain attenuation, and if it continues to be transmitted to the ground floor, it will produce an amplification effect, and the vibration is about 3.6~5dB. The attenuation of vehicle-induced vibration transmitted in the station building is small, and the vibration attenuation mainly depends on the soil layer, and the vibration attenuation is about 0.53 dB/m. The research results can provide a reference for vibration prediction, vibration comfort evaluation and vibration reduction design of subway stations and buildings with similar structures.
