| Abstract: | The numerical simulation technology was used to study the dynamic behavior of a high-intensity earthquake on a double-arch and neighborhood tunnel.The Xudianzi Tunnel is taken as an example.The change of displacement and internal forces of the lining structure are simulated at the portal and analysed along the vertical direction.The seismic dynamic responses of the double-arch and neighborhood tunnel are summarized at last,thus providing a basis for shock absorption in the design of similar tunnels. |

| Keywords: | double-arch neighborhood seismic dynamic response peak of displacement peak of internal force |
