In this paper is presented the results of calculations of reinforced concrete structure of metro station in the form of cupola located at the intersection of interstation tunnels. The constructive solution of station is economical, allows diversifying its architecture and using the internal space for placing objects of the national economy. One of the important design stages is the assessment of the stress-strain state of structure with different boundary conditions when it is exposed to external loads. It is assumed that deformable environment surrounding the tunnel station is elastic and is modeled by discrete bearing reaction located in contact with the station. The structure is modeled by finite shell elements. As the result of calculation the principal stresses and moments in its sections are determined. The obtained data can be made by designers in determining of structural solution, dimensions and initial sections selection of reinforcement elements.
