Abstract:

For most of the tunnels, the rock-support interface can vary between some full-slip to a non-slip condition, so both types should be investigated for static lining forces and deformations. In dynamic analysis, these conditions have a deterministic role on the interaction between the tunnel periphery rock mass and tunnel lining and evidently, on the load transfer intensity between them. In this paper, a dynamic analysis of tunnels under different conditions of the rock mass and lining interface has been carried out by analytical and FEM numerical methods. Also, the effect of the interface between tunnel lining and surrounding medium on earthquake intensity studied. In the following, the numerical results are verified based on an analytical method. The numerical and analytical results have a meaningful agreement with themselves. Results also showed that tunnel lining is more confronted with the induced stress due to the earthquake shake forces in non-slip condition, while in medium it is the other way around
