析地铁车站防排烟系统性能检验

摘要

This paper analyzes the characteristics of subway fire and the smoke hazard.It shows that the detection of downward air current from the station hall to the platform is necessary besides conventional smoke control system detection,so that the effect of smoke exhaust system can be accurately assessed and the passenger protection can be improved.%通过对地铁火灾特点、地铁火灾烟气危害的分析,对地铁车站提出了除了要进行常规的防排烟系统检测之外,还要检测站厅到站台的楼梯和扶梯口处的向下气流,准确地评价其实际防烟效果,以保障乘客安全.
