Discussion on the design of subway smoke prevention and exhaust

In this paper the importance of the smoke control system design in the subway fire introduced,and some existed problems and relevant solutions,in current domestic subway,in the design of the smoke exhaust volume calculation,the choice of the models of smoke exhaust in the tunnel,the design of the location between the air pavilion and the passageway,etc were presented also.Combined with the quoted experiments and its conclusions,after the above analysis and summary of relevant issues,aimed at subway stations and public areas of the exhaust tunnel mode and exhaust devices,some suitable measures in the smoke control system construction in domestic subway fire were put forward.Finally,the conclusions came out after analysis of the measures proposed according to reference test.
