Abstract
The high volume of traffic and limited surface space have led to the expansion of the use of underground communication routes in urban areas. The expansion of transportation in metropolitan areas also involves the construction of underground structures to reduce traffic load and facilitate traffic. Considering the use of tunnels and their importance, it is necessary to examine the dynamic response of tunnels to dynamic earthquake loads. With the construction of numerous tunnels, the behavior of tunnels under the influence of seismic loads has become more important. Usually, in the seismic analysis of underground spaces, the response of the underground structure to a possible earthquake is predicted based on the results of seismic hazard analysis and by specifying the maximum acceleration values of the earthquake and applying the corresponding time history to the numerical model. The study showed that the seismic design of these structures and the prediction of their failure levels are important, because damage to these structures leads to the blockage or failure of the communication route, which in turn will lead to significant losses and damages. In the parametric study, the interaction of the two-story tunnel and the soil is investigated. In the two-dimensional finite element analysis, which includes the soil stiffness around the tunnel, and the effects of the tunnel under construction in stages on the displacement, torsional moment and axial force applied to the final tunnel lining are investigated. The finite element software PLAXIS 3D has been used in the analysis.
In underground structures such as tunnels, it is important to choose a suitable behavioral model for the soil that can accurately behave in accordance with reality. To evaluate the dynamic performance, the Mohr-Coulomb behavioral model has been used
