According to the reality that some tunnel entrances of Wudu-Guanzigou expressway need passing through the provincial road S201 and thinking that upper part of the tunnel is going to bear vehicle load and the relationship of the lining with the surrounding rocks, this paper adopts ansys 8.1 to build the finite element model and carries out the numerical simulation of the tunnel. The calculation indicates that the borne force of the linking locations at the relying on invert, and the on the invert and the bend wall is maximal.
