轨道交通区间隧道运动列车实体冷烟试验

Cold Smoke Test of Running Train in Rail Transit Tunnel

介绍了轨道交通列车运行过程中着火并迫停在隧道内时的烟气迁移冷烟试验情况,验证了烟气迁移规律。该试验对不同纵向通风方向的控烟效果进行了定量评估,分析了车门、空调启闭时的疏散环境和疏散行为;积累了列车运行过程中的烟气探测、联动设备操作可行性经验。

When a train is forced to stop in interval tunnel because of catching fire,its smoke movement has certain regularity.A cold smoke test was conducted in an interval tunnel to verify the smoke movement regularity of running train.The quantitative assessment was made to the smoke control effects by longitudinal ventilation in different directions.The evacuation environment and evacuation behavior when train door and air conditioning are on/off were analyzed.The operation experience of smoke detector and other linked equipment was accumulated.
