Analysis on Ground Vibration Induced by Subway under Three Track Structures

Abstract:

On the purpose of investigation for damping effect of different track supporting, In-situ experiments of vertical ground vibration acceleration induced by underground railway traffic under three track structures were performed at line 8 in shanghai. Time history and 1/3 octave for ground vibration were analyzed and the variation between ground vibration and track supporting structure as well as train velocity was summarized. The results show that reducing vibration effects of different track structure is determined to its own stiffness, various track velocity has little influence to VL_zmaxof ground vibration. The study result in this paper has important theoretical significance and reference value for the application of track structure in vibration reduction of subway.
