Study of the influence of spatial effects on the ground surface and buildings in a two-lane tunnel boring.

With increasing spacing, the axial force, shear force and bending moment of the plate and column structure of the building show a decreasing trend, among which the maximum axial force of the plate structure is 1365.7 kN, the maximum shear force is 1031.6 kN, the maximum bending moment is 400.6 kN m, the maximum axial force of the column structure is 5012.6 kN, and the maximum shear force is 474.5 kN.
