Based on the principle that the forces under the steel spring are kept coordinated, the subway cars-floating slab track coupling dynamic model and the tunnel-buildings-foundation two-dimensional dynamic finite element model are established to discuss the distributing characteristics of the damping region in the integrated construction after foundation reinforced with cement-soil piles and the law that the vibration-damping effect changes with the distance to subway loads and the critical width of reinforced foundation. The main conclusions show: (1) after both sides of the tunnel are reinforced, the integrated construction is divided into the vibration-damping region and vibration-rebounding region, and the distance from the boundary between the two regions to subway loads has something to do with the intensity of the floors above the tunnel; (2) the changing extent of vibration-damping effect in the vibration-damping region is influenced greater by the horizontal distance than by the floor height and span of floor slab, and seems to show a fluctuation; (3) after the width of reinforced foundation at both sides of the tunnel reaches a certain magnitude, if it is further increased, its vibration-damping region can be appropriately expanded, but its damping efficiency can not be significantly improved.
