Doolayi Tunnel is located in Toyserkan is one of the strategic tunnels that connect Hamedan to west provinces of Iran. This tunnel was excavated in proximity to Sannandaj-Sirjan active fault, is exposed to landslide hornfels stone and groundwater . It means that due to occurrence of possible destructive earthquake in this region tunnel demolition, as a result of undesirable geology conditions is definite. In this article dynamic behavior of 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 using of composite system, in addition to make dynamic stability of tunnel; significantly decreases displacement, swelling, settlement, stress and shear stress.
