The subject of the publication is the modeling of a tunnel metro section in a calculation program, which is based on the finite element method. An analysis of the obtained results for the stress and strain state in the massif during the passage of the tunnel through the section was made. The data on the surface deformations obtained from the model are compared with those actually measured during the monitoring of the construction and sizing of the primary cladding.
