Dynamic Response of Segmental Lining Tunnel



This article presents an investigation into the seismic response of a shallow-buried tunnel in rock. The tunnel had two sections. One section was lined with prefabricated segments and cast-in-place inner lining, and the other section was lined with only prefabricated segments. A series of shaking table tests simulated the seismic response of the segmental lining tunnel. Test cases considered different input directions, two earthquake intensities, and two earthquake motions. Accelerometers measured the acceleration response of the tunnel structure. Numerical simulations were also employed to validate the test model and to study the deformation of the tunnel structure. Based on the test results, the dynamic responses at the arch crown and invert were presented, and then the acceleration, Fourier spectrum, and Arias Intensity were selected to discuss the dynamic characteristics of the tunnel in different cases. The results showed that the seismic responses in the direction perpendicular to the exciting direction were negligible when one-way input motion was applied. The arch crown showed larger accelerations than the invert, with the differences of 13.1 % and 5.0 % at the section without inner lining and the section with inner lining, respectively. The peak acceleration of the section with inner lining was 34.2 % larger than the section without inner lining in the transverse direction; whereas the inner lining had small influences on the accelerations in the longitudinal direction. In addition, the inner lining was able to reduce the deformation of the tunnel; especially, the joint extension at the section with inner lining was only 33 % of the extension at the section without inner lining.
