| Abstract: | The computing precision of three type conditions such as viscous-spring boundary, viscous boundary and fixed boundary is compared. Based on various boundary conditions, the seismic response studies of a tunnel are executed by using vibration-method and wave-method respectively. The influence of infinite foundation soil to the earthquake responses of the tunnel is researched and the weak parts in liner are determined. |

| Keywords: | viscous-spring boundary tunnel earthquake finite element method |
