Abstract: Usually in the area with dense and intensive buildings, the construction of shield tunnel will influence the subsiding of adjacent building. In view of the structure’s different foundations, FEM is adopted in this paper to study and simulate on shield tunnel construction of adjacent structure. It is indicated as follows: With different forms of building foundation, their influence on tunnel lining’s force status are different. Tunnel lining undertakes greater internal force during the construction of nearby shield tunnel. In the condition of shallow foundation, tunnel excavation takes more affect on the building. But adjacent base side of tunnel excavation internal force changes relatively samll in building with pile foundation

Key words: shield tunnel, structure, numerical simulation, foundation types, internal force
