Insufficient experience in emergency planning and insufficient fire protection are part of the problems. At present the length of Taipei underground railway has reached more than 15 km. The study of smoke management and evacuation shall thoroughly be performed for the longer tunnel. In case of train fire in a double-track tunnel, the topic of escaping from the nearby non-fired track across the scene of fire to reduce the escaping distance and the harmful effects should be considered for various fire intensities. The evacuation should also be considered along with the emergency mode of tunnel ventilation. This study examines and compares the critical air velocity with the field measured data under an emergency operating mode. The NIST developed FDS (Fire Dynamics Simulator) program was used to simulate and analyze the smoke flow and other fire conditions. This study examines the computer calculation results on the basis of NFPA130. Proper recommendation for safe refuge is proposed. In addition, the calculation of safety time for safe passage across the scene of fire for various fire scenarios. The smoke management for the operation and security of long underground railway tunnel is discussed and analyzed. The results of this study could be used as a reference for planning, designing and constructing the underground railway project.
