Seismic Response Study of Tunnels Running underneath a Subway Station in Parallel by Fuxue Sun, Guo-bo Wang, Xiang-jun Peng, Zhou-zhou Jin, Xiao-chun Li, Jie-lin Zhao

“…The range of influence of the station structure on the surface is approximately five times the width of the station, and the surface response is obviously significant within this range. (2) The existence of the tunnel is conducive to reducing the acceleration of the column in the station. It increases the displacement difference between the stations, but the impact on the internal force of the station is not significant. (3) The influence of the station on the dynamic response of the tunnel is consistent with regard to tunnel acceleration, difference in displacement between the top and bottom of the tunnel, and internal force. …”
