Article Preview

With regard to road tunnel fire situation, the smoke extraction system is very important for effective control of fire temperature as well as crowd safe evacuation. The section form of smoke outlet is one of the main factors affecting smoke extraction. Taking a certain large scale cross-section road tunnel as physical model, this paper carried out simulation analysis on several fire scenarios with the help of software FDS. By comparing with different flow rates of each section of smoke outlet as well as the corresponding calculated danger approaching time, the appropriate smoke outlet section was attained which could be a reference for practical projects.
