Abstract
Doolayi Tunnel, located in Toyserkan, is one of the strategic tunnels that connect Hamedan to the western provinces of Iran. This tunnel was excavated in proximity to the Sannandaj-Sirjan active fault and is exposed to landslide hornfels stone and groundwater. It means that, due to the occurrence of possible destructive earthquakes in this region. tunnel demolition - as a result of undesirable geology conditions - is definite. In this article, dynamic behavior of a tunnel is studied by FLAC 3D V3.00 software. Moreover, an optimum arrangement of rock bolt and reinforced Shotcrete is proposed to be able to have the most stability against accompanied effects of quake and groundwater. The results of this study indicate that the use of a composite system - in addition to making dynamic stability of the tunnel - significantly decreases displacement, swelling, settlement, stress and shear stress.
