Abstract
As a safer and faster means of transportation, the high speed railway grows rapidly around the world. However, the vibrations generated by high speed train (HST) draw more and more attentions from the researchers. Moreover, the experimental investigations of HST induced ground vibrations simultaneously in three directions are rare. So, this paper studies the vertical, perpendicular and parallel ground vibrations on the Beijing-Shanghai high-speed railway through the field experiment. The characteristics of ground vibration accelerations in both time and frequency domains are then analyzed. Moreover, a further discussion about the results is presented. The results show that the vibration rules in three directions are similar. The vibration amplitudes of the surrounding ground attenuate with the distance from the track centerline. And an amplify zone of ground vibration is clearly observed at about 24 m from the center of the lines. The main vibration frequency is at the range from 20 to 50 Hz.
