摘　　要：为了研究烟气在地铁车站隧道内的蔓延特征,及在车站隧道通风排烟系统、区间隧道通风排烟系统及车站公共区通风排烟系统联合排烟情况下烟气控制效果,在一地铁车站隧道内开展了全尺寸火灾实验。实验研究了车站隧道顶部横向排烟作用下的烟气扩散规律,及烟气的温度变化,分析了屏蔽门开关状态下烟气与空气的卷吸混合特性,及区间风机的气流组织对通风排烟的影响。实验结果对于地铁车站隧道火灾防排烟设计提供了数据支持。In order to investigate the spreading characteristics of smoke in case of fires in a metro station tunnel, and the smoke control effect with the operation of the ventilation and exhaust systems in the station tunnel, the interval tunnel and the station public area, full scale fire experiments were carried out in a metro station tunnel. Based on the experimental results, the smoke spread and control effect under the top lateral exhaust in station tun- nel was investigated. Furthermore, the temperature distribution characteristic, the mixing of the gas and the air under different shielding door switch status, and the influence of airflow organization by interval tunnel fan to smoke exhaust were also analyzed. The experimental results will provide data support for the smoke ventilation system design of the metro station tunnel fire.
