Analysis of Longitudinal Seismic Response of Shield Tunnel

  • In order to investigate the characteristics of longitudinal seismic response of shield tunnels,the seismic response of a shield tunnel across the Yangtze River in Wuhan was investigated with a three-dimensional finite element model for ground-tunnel interaction.The investigation mainly concerns the reasonable mechanics model,the interaction between tunnel and ground,and the vibration characteristics of tunnels.The research obtains the distribution of displacement and stress and their time-dependent curves.The numerical results show that the key points in the aseismatic design of tunnels are the tension and compression stresses in the longitudinal direction of tunnels under a compression wave and the torsional displacement of tunnels under a shear wave.
