| 摘 要： | 为了研究强制通风情况下地铁区间隧道火灾时的烟气扩散规律,在一实际地铁区间隧道内开展了全尺寸火灾实验。实验改变火源功率,在区间隧道通风排烟系统启动状态下,研究了区间烟气纵向蔓延速度、烟气竖直温度分布和水平温度变化,分析了烟气火焰倾斜角,顶棚烟气温升的纵向指数变化特征。实验结果对于地铁区间隧道火灾烟流控制及防排烟设计提供了数据支持。

| Abstract: | In order to investigate the smoke spreading characteristic of metro tunnel fire under forced ventilation condition, full scale fire experiments were carried out in an actual metro tunnel. Fire power was altered, with the operation of the interval tunnel ventilation and exhaust system, the longitudinal smoke spread speed, vertical distri- bution of the smoke temperature and longitudinal change of smoke temperature were studied, based on that, the de- flection angle of the flame and plume, the index variation characteristic of longitudinal ceiling smoke temperature rise were analyzed . The experimental results will provide data support for the smoke control and ventilation system design of the metro tunnel fire. |
