Abstract：The shield tunneling is a future main method of the subway tunneling in the city. The success experience and technique have been achieved in our country, but the theoretical and technical problem still need be solved in the field of geology engineering relate to the shield tunneling. In this paper, the problem of the surface subsidence about the shield tunneling and the estimation method of range of surface subsidence is studied, according to existing documentation and success experience. Based on this, the viewpoint that main reason of generating the surface subsidence is the subsidiary stress in the process of the shield tunneling, and the comprehensive analysis should be applied to the estimation method of range of surface subsidence are presented. The effect of the subsidiary stress on surrounding structure and stratum layer is set forth.
