Summary:A calculation and analysis method for ground surface settlement caused by pipe shed pore-forming disturbance comprises the steps that S1, the deformation mechanism and stress of a pipe shed are analyzed, and a calculation model is set; s2, tunnel burial depth and soil layer structure parameters are obtained according to the calculation model and the construction working conditions; s3, the pipe shed is approximated to be a small-hole tunnel, and a Peck formula is adopted for calculation; s4, applying a Peck formula for calculating the ground surface settlement to calculate the ground surface settlement caused by the pipe shed pore-forming disturbance, substituting a plurality of pipe sheds into a large circle, and combining a plurality of small holes; s5, determining a disturbance coefficient between the pipe sheds, and selecting actual measurement data for fitting; and S6, considering the bending and compression deformation of the pipe shed, proposing a corresponding formula, and calculating to obtain the di
