Abstract
3d finite element model of soil and prefabricated tunnel lining interaction with appropriate boundary condition is given in this article. Stresses distribution on inner and outer part of the tunnel lining is analyzed. Relationship between stress state at top and sides of the tunnel lining and deformation module magnitude is shown.
