Abstract: Taking a frame structure office building for example, a 3D nonlinear constitutive model regarding the building and its foundation with cavern as a whole and taking into account the tunnel-soil-structure interaction is put forward by means of general FEM program ANSYS10.0. Its differential settlement and variation of internal force due to the passage of a shield tunnel is investigated. The result indicates that major settlement of the foundation of the building occurs in the zone where the shield tunnel passes through the building; its transverse obliquity increases along with the shield advance, while its longitudinal obliquity reaches the maximum when the excavation face is close to the centerline of the building; during the passing course the equivalent stress of columns can rise by 20.1 % at most; torque of structural components changes more obviously compared with their bending moment; its deformation and internal force tend to be constant when the excavation face overpasses the building for 20 meters.

Key words: metro tunnel, adjacent building, finite elements, settlement, internal force
