Abstract

Under the background of Songhua river tunnel project to be built in Harbin

this paper focus on the material nonlinearity of soil mass and linings as well as interactions between them.Some FEM calculation models are established under different site conditions based on plane strain assumption.The distributions of soil displacement around the tunnel under different site conditions are researched by numerical calculation with ANSYS.Some key factors which influence the soil deforming around the tunnel are defined and theoretical references are provided to determine the safety thickness of overburden of the tunnel.
