Analysis of Settlement of Buildings Induced by Shield Tunnels Under Construction
Shield construction will cause soil deformation around the tunnel, and settle and tilt existing buildings on the ground. Aimed at the construction conditions of the flood plain stratum in Fenhe River and the shallow foundation building under the shield in Taiyuan area, this paper carried out the com...

| description | Shield construction will cause soil deformation around the tunnel, and settle and tilt existing buildings on the ground. Aimed at the construction conditions of the flood plain stratum in Fenhe River and the shallow foundation building under the shield in Taiyuan area, this paper carried out the combination of 3D numerical finite difference software FLAC3D simulation and field monitoring to aualyze the in fluence of the existence and stiffness of buildings on settlement laws. The results show that the existence of building has a small effect on the formation of lateral settlement tank, the settlement process is very different with respect to the absence of buildings; The presence of buildings constrains the surrounding soil, and lead to the hysteresis and integrity in buildings and surrounding strata during settlement; The changes in building stiffness have less impact on settlement lag, and greater stiffness results in stronger integrity. The research results can help predict the deformation of buildings and surrounding strata during shield construction. |
