The deformation convergence and the section shape measurement of the tunnel in the construction monitoring measurement are parameters which must be measured, the stability of the surrounding rock structure is judged through the section convergence of the tunnel, and the excavation quality (whether the excavation exceeds the underpass) of the section of the tunnel is evaluated through the measurement of the section of the tunnel.
