Numerical Simulation for Surface Displacement of Shield Tunnel Construction under Building Load

Abstract:

The tunnel construction causes deformation, even damage of the nearby buildings and other types of structures. Using 3d finite element method can simulate the process of shield tunneling construction. The paper studies the influence of different building load on the deformation of soil, when considering different excavation steps in the process of tunnel construction. The results show that the building load has important influence on the surface displacement during the construction of tunnel. With the advancement of excavation, sedimentation tank will move forward and become larger. By the influence of jacking force, the soil and rock in front of tunnel face moves forward and upward, thus forming the surface uplift.
