地铁车站双存车线处的烟控系统研究
Research on smoke control system of double storage siding of an underground railway station
摘要：
借助火灾模拟软件FDS，对地铁车站双存车线处的半横向排烟方式进行了模拟研究，分析了不同排烟口设置形式、排烟口间距和排烟量等关键技术参数对排烟效果的影响。推荐采用大风口形式的半横向排烟系统，排烟口间距为40 m，排烟量不小于45 m3/s。

Abstract：
Based on the fire simulation software (FDS), studies the semi transverse ventilation mode of the double storage siding by simulation. Analyses the influence of key technical parameters on smoke exhaust efficiency, such as smoke vent form and spacing and smoke exhaust volume, etc. Recommends that the semi transverse ventilation system with large vents, smoke vent spacing of 40 m and smoke exhaust volume of 45 m3/s should be adopted in the underground railway station.
