Abstract: Through the in-situ measurement of the environmental vibration caused by the maglev train in Shanghai, the decay of the vibration with distance and depth is analyzed. The results show that the vibration caused by maglev train decreases with distance, and the dominant frequency of far-field vibration is 3~6 Hz. The material damping of soil plays a certain role in the vibration decay and it cannot be ignored, especially in the far field. The Bornitz’s theoretical prediction formula can accurately predict the vibration with distance in general, although there is an overestimation of 2~8 mm/s² in the near-field region. The vibration in far-field at the depth of 5 m is amplified compared to that of the ground. Regarding the vibration amplitude along the depth, the elastic analytical solution may underestimate the actual vibration.
