The paper describes the results of a numerical analysis of reinforced concrete tunnel lining in four characteristic cross-sections, taking into account different modelling methods. The calculations were performed with the use of the finite element method and GEO5 FEM software using data from the design works related to the planned construction of the technical tunnel under the river Vistula. Owing to significant differences in momentum values, the conclusions from the study will be used to define the joints between tunnel segments and to dimension the tunnel lining in the technical design of the structure.
