Dynamic Response Analysis of the Subway Station Under Moving Train Loads
With the rapid development of urban mass transit systems, the issue of train-induced vibration has attracted attention. The train-induced ground vibration that occurs above or near a train station is different from that which occurs above the main line due to key differences in structure, as well as the layout of turnouts. In this paper, in order to model trainloads at the main line and turnout areas, the authors used a simplified two-dimensional train-track coupled model and an additional three-dimensional station-soil finite-infinite coupled model, and the latter was created using the software ABAQUS. The station’s structural dynamic responses at both the turnout areas and the main line were calculated, and the time and frequency data were compared. The authors' results show that when the train passed through a track with turnouts, the acceleration response on the rails was ten times larger than when it passed through the main line, and the acceleration response on the sleepers was five times larger than when it passed through the main line. The acceleration response of the station plate exhibited the most dramatic decrease at frequencies between 3 and 20 Hz and between 60 and 100 Hz. Furthermore, the vibration through the plate decreased over entire frequency bands, and vibration through the pillars decreased only at frequencies above 50 Hz.
