| Abstract: | The displacement-time history and Mises equivalent stress-time history of deep buried tunnels under the pressure of ground shock wave have been studied by using an engineering software ANSYS. Displacement, deformation and vibration of the tunnels, with different cross sections and surrounding materials, are analyzed. It is found that at certain locations the tunnel structure is more sensitive to the pressure of ground shock wave. Tunnel's behavior of resisting the impact from ground shock wave is affected by the configuration of the tunnel. The protection strategies of tunnel structure are discussed in this paper. |
