Analytical Evaluation of the Impact of Various Parameters on the Forces Acting on a Circular Tunnel Lining under Seismic Loads

In this research، an analytical solution for evaluation of axial force and bending moment in circular tunnel lining due to seismic ovaling deformation has been obtained and the difference in the solution methods for obtaining the axial force and bending moment in non-slip interface condition has been evaluated. The influence of various parameters on axial forces and bending moment have also been studied. In addition، variations of these parameters on flexibility and racking ratio have been determined.
