Taking the subway tunnel passing through residential areas as the engineering background,midas GTX-NX software was used for finite element simulation to analyze the disturbance of tunnel construction on the factory building,and a finite element study on the settlement deformation of separated tunnels passing through buildings was proposed.Research has shown that after the completion of tunnel construction,the settlement of the soil layer in the upper part of the tunnel gradually increases in depth.As the distance from the tunnel axis decreases,the ground settlement gradually increases.It is consistent with the lateral subsidence trend calculated using numerical simulation methods and empirical formula methods.
