Abstract
Abstract This paper carried out the FDS+EVAC simulation to study the metro train fire with relatively large density of passengers. We defined the influencing factors through analyzing the contour of harmful gas concentration as well as smoke temperature. By comparing the Required Safe Egress Time (RSET) with Available Safe Egress Time (ASET), the distribution of evacuation safety was predicted. The results of no casualties reflect that the design of the Over Track Exhaust (OTE) system of the tunnel rail track and the lobby ventilation system is suitable, meanwhile, it may bring some guidance to design the new evacuation strategy for the metro station in fire scenery.
