ABSTRACT
This article contains a method evaluating the stress-strain state in a steel concrete tunnel lining structure of circular and oval shape. The method combines two distinct approaches one numerical and the other analytical. The numerical approach draws stress values from parametric calculations on 3D models representing tunnel lining structures while the analytical approach takes formulae of complex variables. The article provides results of the analysis and achieved findings.

Keywords: tunnel lining, steel concrete cross section, stress strain state
