摘要: The construction of tunnels in carbonate karstic rocks has always been the most hazardous and problematic task civil mining engineering, as it can threaten tunneling project from safety, time economic aspects. Therefore, is essential to identify hazards resulting early stages a project. present paper aimed main geological related Zagros Mountains. process identification relies upon review experiences obtained several projects with focus on Kuhrang Tunnels. Obviously, groundwater inrush tunnel flooding, ground inflow fill-back tunnel, instability weak fill materials, TBM jamming are potential Mountains, imposing huge problems during construction. Inadequate understanding not being prepared enough take appropriate countermeasures sources problems. In addition, investigation study provides guidelines reduce risks similar condition.
