| In this paper, based on an island platform of a double-subway station, FDS was used to simulate the fire scenario of luggage fire close to the stair in the middle of platform, with different ventilated exhaust mode. Temperature and smoke concentration were analyzed, and results were compared. The results showed that without mechanical smoke exhaust, smoke drop to 2m above the floor ground at about 600s and any stairs is unavailable, while each stair is available for evacuation when smoke exhaust is on; the validity of platform smoke exhaust is critical to the control of fire development and evacuation safety when 1.5MW luggage fire is on in the middle of platform, while train area exhaust and concourse make-up air have little effect on smoke control under this circumstance. |
