Abstract:

According to the execution situation of the tunnel project, the theory of elastoplastic mechanics and the seepage law of groundwater are taken into account; a mathematical model considering seepage-stress coupling of the tunnel is established; seepage and the stress field around the tunnel in different working states are simulated by applying Comsol. The results indicate that during the process of excavation without any measures, deformation of the soil around the tunnel occurs; the deformation of the rock and the settlement of the ground are large; the buildings nearby are in danger and the groundwater infiltrates into the tunnel; the project can’t be conducted; after grouting, the deformation of the rock around the tunnel is reduced and the settlement of the ground is controlled; then the buildings nearby are safe and the tunnel excavation can be processed safely.

Key words: seepage, finite element method, fluid solid coupling, stress field
