主 题：metro double-island platform fire ventilation mode numerical simulation model experiment
摘 要：Large metro transfer stations have been widely constructed in China,among which the double-island station faces the serious fire safety issues owing to its large passenger *** this paper,simulation cases were carried out to investigate the effectiveness of different ventilation modes by jointly operating tunnel ventilation fan(TVF)and platform screen doors(PSD)under two typical fire scenarios in the *** numerical model was established by Fire Dynamics Simulator software and verified via reduced-scale model *** results indicate that the TVF mode of supplying at the end near fire and exhausting at the other end is superior to that of exhausting at both ***,activating more PSD and TVF on the both sides of platform will restrict smoke in one end to the greater *** a fire in the middle of the platform,opening all PSD near tunnel-2 and TVF in tunnel-2 and tunnel-3 is the most appropriate *** during a fire at the left end of the platform,activating all PSD and TVF on both sides is the optimal operation *** conclusions can provide guidance for smoke control design and on-site emergency ventilation operation in double-island platform fire.
