that the setting of the support is necessary and effective, the small section tunnel converges only 5 mm after the auxiliary scissor is added.Р5.5 Information ConstructionРIn order to ensure structural safety and construction safety, real-time monitoring measurement is carried out during the tunnel construction process. The deformation characteristics of supporting structures and surrounding strata are used to predict the corresponding support structure displacements and to verify the rationality of supporting structures to provide a basis for information construction. Monitoring during construction shows that the maximum settlement of a tunnel with a small cross section is 14.6 mm. The maximum settlement of a tunnel with a large section is 17.2 mm. The maximum convergence of the tunnel is
