Abstract
The earthquake causes serious damage in the tunnel. Many factors control these damages such as soil type, seismic intensity and the properties of the tunnel wall. In this research, the effect of the thickness of the circular section was studied under seismic loads. Finite Element Analysis was used to demonstrate the behavior of tunnel wall using Materially Non-Linear Analysis (MNA) for both the soil and the lining. This research shows that using inelastic analysis for the lining provides higher local damages. Moreover, it is concluded that a critical thickness is related to the intensity of the earthquake. At this critical thickness, earlier collapse can be occurred.
