Numerical Simulation of Subway-Induced Environment Vibration

Abstract:

The ABAQUS software was used to establish an actual soil layers-tunnel model in which the infinite element boundary was adopted. Then, frequency domain analyses were conducted on the model under vertical train loads with different frequencies. The attenuation of the vertical displacement amplitude on ground surface under each load was computed in the area ranging from 0m to 30m. The results show that the displacement amplitude may rebound in a particular area under some loading frequencies and this phenomenon is closely related with the loading frequency.
