Abstract :

Background and Objective: Urban Expansion and problems regarding urban life raise the necessity of providing actionable strategies to improve urban inhabitants’ life. Today, with increasing tunnel constructions, safety in tunnels has been the issue for engineers, government officials and authorities. In order to standardize and safety enhancement, safety assessment is the first priority to adopt relevant measures to improve safety level in tunnels. Generally, regarding to the limited spaces in urban tunnels, accidents in tunnels may result in more critical conditions. Occurring of these accidents may disturb the tunnel’s function, which may lead to fire, respiratory problems etc. Given to critical condition after the accidents, therefore, it is required to adopt appropriates methods for safety factor assessment in crisis management of tunnels. The present study address safety and biological factor assessment in crisis management of urban tunnels after that we would investigate the differences between Tohid, Resalat and Shohadaie Qazeh tunnels. Method: To analyze data, Analytic Hierarchy Process (AHP) has been used. Findings: The highest level of risk associated with Tohid tunnel and the lowest level of risk associated with Shohadaie Qazeh tunnels. Discussion and Conclusion: The results of research in 1396 show that the ventilation system has the highest weight and drainage has the lowest weight and Tohid tunnel has the first rank.
