摘要：

Fire accidents in a cross interchange subway are analyzed. At present, the primary focus of subway evacuation behavior analysis is mainly concern on normal state; evacuations in case of fire have rarely been under research. The relationship of soot density and extinction coefficient of fire smoke with average walking speed of occupants is linearly dependent. In this paper, FDS+Evac program is used to simulate the evacuation in a fire scenario. It has been found that not only some occupants' evacuation routes become longer, but also the utilization of some of the exits is reduced, therefore congestion is caused at other safe exits in a cross subway station fire.
