地铁火灾防排烟设计探讨

Discussion on the design of subway smoke prevention and exhaust

介绍了防排烟系统设计在地铁火灾中的重要性,以及目前国内地铁车站在防排烟设计中有关排烟量的计算,区间隧道的排烟方式,排烟风亭与出入口之间的位置设计等方面所存在的一些问题及相关的解决方案。结合所引用的相关试验研究及其结论,经过对上述相关问题的分析和总结,针对地铁车站公共区和区间隧道的排烟方式和排烟装置,文章提出了适于国内地铁消防防排烟建设的措施,最后根据所引用的试验,对所提出的措施作出了分析,以得出结论。

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.
