The design of tunnel lining requires a proper estimate lining forces. In engineering practice different design methods tend to be used, varying from simple empirical and analytical formulations to advanced finite element analysis. This paper begins with a review of empirical and analytical analysis for tunnel lining forces and materials, followed by the design methodology, the analytical results and the concrete design of the tunnel lining using structural software known as STAAD Pro. The scope of this research is mainly focused on the analysis and concrete design of the tunnel lining. Finally, the results obtained are carefully shown in this paper and performed by mean of two different approaches: a tunnel lining analysis and a concrete design results, showing the excellent accuracy achieved in terms of displacements, stresses, reactions, bars criteria and main reinforcement.
