Wise highway network is one of the most important routes along the east-west highway in Tehran considered the westernmost point of the easternmost point of access enables regional and local. This highway in the eastern part of Tehran highway in the western part of the mission and the highway is wise. Wise in the tunnel area along Highway 22 between Highway Tehran Iran war to the intersection of automobiles, part of the highway from Forest Park Cheetgar passes, tunnel consists of two round trip with three lines on each side of the crossing. Given the importance of this tunnel aware of the function of these structures is important in times of crisis. From the dangers that threaten these structures earthquake-up can be named. Earthquake near the tunnel may cause a lot of damage. In recent years, the development and frequency of seismic damage underground structures, seismic analysis and design of underground structures has been more and more attention. Especially in large-Osaka Kobe earthquake in 1995, some subway stations and tunnels were severe injury, the first about the damage caused by the earthquake is the modern amenities underground. After this, the scientists examined the underground seismic and thereby causes damage theory based analysis and design methods to be carried out. Extraordinary efforts to advance the underground seismic studies, the important instructions provided in the field of earthquake engineering. So study the effect of an earthquake on the tunnels is required. In this study, using the software PLAXIS the effect of an earthquake on a specific section of the tunnel has been wise. This means that performance wise tunnel earthquake was examined.
