Abstract

The environmental vibration problems caused by the operation of subway trains are becoming increasingly prominent. In order to master the influence of line conditions on the vibration characteristics of the subway under high-speed driving conditions, field test of track vibration on a curved section of the subway at a speed of 120 km/h was carried out. The vibration characteristics of ordinary tracks under different curve radius conditions were studied, and the vibration transmission laws were analyzed. The results show that the maximum Z-vibration level range of vertical vibration of the tunnel wall is 56.00dB~73.36dB when subway trains pass through a 750 m curve radius line. The maximum Z-vibration level range of vertical vibration of the tunnel wall is 51.18dB~63.32dB when subway trains pass through a 2000 m curve radius line. Compared with the 2000 m curve radius line, the amplitude of vertical vibration of steel rails and tunnel walls increases significantly in the low-frequency range when subway trains pass through the 750 m curve radius line, and the average value of the maximum Z-vibration level of vertical vibration of tunnel wall increases by 9.10dB.
