Comparative study on experiment and simulation of screen door open modes under underground railway platform fire situation

Taking Datang station of Guangzhou underground railway line three as an example, adopting experiment and simulation methods, analyses the wind velocity and quantity through screen doors on the platform of standard interval station under five screen door open modes when fire occurs on the platform, and studies the best screen door opening scheme. The results show that when the number of open screen door is 2,4, 6 and 24 (all open), it can meet the evacuation requirements, and also comply with the relevant specifications when the fire occurs on the platform.But the best opening scheme is that two doors are open on the two sides of the platform, in addition to opening the exhaust fans.
