Abstract
This study deals with the analytical solutions for the thrust and moment in the lining of a circular tunnel due to seismic-induced ovaling deformation. The discrepancy among the existing solutions in the thrust and moment for no-slip interface condition is investigated. New analytical solutions are developed by considering the relations between displacements and interaction forces at the soil-lining interface and including the slippage effect at the soil-lining interface using a spring-type flexibility coefficient. The comparison among the solutions in the thrust and moment is discussed. The effects of flexibility coefficient and deformation ratio are investigated.
