Abstract: By taking account of a building project in Chongqing, the authors adopt a structural analysis program 2D-σ to analyze evolvement regulation of the stress in the rock-mass related to a tunnel and a upper structure in four kinds of typical building step. The result indicates that interaction may exists between the tunnel and the upper structure; and the stress distribution come into being a break near the tunnel; and the tunnel side wall is compressed; and the tunnel arch is tensioned. The result will provide the references for the tunnel and the upper structure.

Key words: finite element method, tunnel, foundation
