Abstract
In order to strictly control the impact of geotechnical operations on surface buildings through the shield method, the influence of shield tunneling on the settlement of buildings around the construction area during the tunnel excavation process is analyzed. The actual engineering case is used to analyze the engineering examples by using 3D numerical simulation and empirical numerical calculation by MIDAS GTS NX finite element software. The analysis results show that the influence of the shield method on surface buildings is related to distance. The influence law of shield tunneling on the construction of geotechnical tunnels is analyzed, and it is concluded that it will lead to surface settlement when the subway tunnel is excavated by shield tunneling; in the case of shallow burial, the foundation of the building within the depth of the tunnel needs to be treated as necessary; buildings outside the depth of the tunnel are generally not affected by the construction.
