Abstarct: A variety of factors can be effective on settlement of the tunnel. Awareness of the effect of each of these parameters can prevent or reduce any damages. In most previous studies, Shotcrete's behavior modeled with the plate element and has constant stiffness during the analysis, while the behavior of the Shotcrete is time dependent. In this study, simulation of the Amir Kabir tunnel in Tehran has been considered and compared the behavior of lining while modeled with the plate method and the concrete behavioral model. The results of this study showed that the use of concrete behavioral model can lead to a 20% reduction in tunnel crown settlement during analysis and under constant conditions and would be better in compare with reality. On the other hand, the ratio of one -day to 28 -day concrete can increase the settlement around the tunnel by up to 58% and increase the uplift up to 110%.
