摘 要: 以重庆轨道交通6号线某典型双层岛式地下车站为依托,开展火灾热烟实验。并结合数值模拟的方法,分析车站发生火灾时,不同通风排烟模式下的烟气流动及烟气温度分布规律。验证了Alpert模型,并提出车站火灾发生时的最佳通风排烟模式,以期为地铁车站通风排烟系统的设计和运行方式提供参考。
关 键 词: 通风与空调工程;通风排烟模式;数值模拟;地铁车站;火灾

Abstract: A full-scale hot smoke experiment has been conducted in a double-deck island platform station in Chongqing No.6 metro line. When the metro station sets fire, adopting the method of numerical simulation, the smoke flow status and the smoke temperature distribution in the station have been assessed. Meanwhile, the Alpert model has been verified. The best smoke control mode is proposed in order to provide a reference for the operation and design of smoke control systems in metro systems.
Key words: ventilation and air-condition engineering; ventilation and smoke extraction mode; numerical simulation; metro station; fire scenario
