摘要
为研究地铁站通风排烟系统的有效性,以某地铁站为原型,利用FDS对地铁区间隧道火灾与站台火灾进行数值模拟,得出站点内烟气温度、有毒气体浓度(以CO为主)、能见度,烟气层高度等特征参数的分布规律,分析深埋地铁站通风排烟系统的设计安全目标,探索有效性评估分析的手段和方法。
In order to study the effectiveness of ventilation and smoke exhaust system in subway station,taking a subway as prototype,the tunnel fire and platform fire in subway station were numerically simulated by FDS.The distribution laws of smoke temperature、concentration of CO、visibility and smoke layer height were obtained.The design security objectives of ventilation and smoke exhaust system of deep buried Metro station was analyzed,and the means and methods of the effectiveness assessment analysis was also explored.
