Comparative Testing on Ground Surface Vibration Caused by CRH Trains Running on Viaduct and Embankment
Based on the measurement of the vertical velocity of ground surface vibration caused by CRH trains running on viaduct and embankment of Hu-Ning Intercity Railway, the characteristics and propagation attenuation rules of the ground surface vibration of two routes are analyzed. The result shows that the main frequency of ground surface vibration caused by the CRH trains running is less than 80Hz, which belongs to low frequency vibration. The number of carriages has little effect on ground surface vibration intensity. The effect of train speed for 153km/h to 201km/h on ground surface vibration intensity has no obvious difference. With the increased distance between the ground surface and the track, the main frequency of ground surface vibration on viaduct decreases, and the attenuation curve of peak value of ground surface vibration velocity becomes smoother. However, the main frequency of ground surface vibration on embankment is nearly unchanged and the attenuation curve of peak value of ground surface vibration velocity has several rebound regions of the vibration. Ground surface vibration intensity of viaduct is higher than that of embankment. The drainage trench built beside the embankment has vibration isolation effect on ground surface vibration.
