地铁隧道通风系统火灾排烟模式的风速试验

本文结合深圳地铁龙华线的实际情况，模拟在实际运营的情况下，区间隧道同时存在3列列车在同一区间隧道内情况下，隧道通风系统能否在火灾工况下火灾模式通风；测试火灾工况下区间隧道排烟系统的排烟效果，并对区间隧道火灾排烟风速测试结果进行了分析，并提出了有关结论，文章对工程设计与管理提供参考和借鉴。

Subway tunnel ventilation system fire smoke pattern speed test

in this paper, combined with the actual situation of shenzhen metro longhua line, under the condition of simulation in the actual operation, tunnel at the same time there are 3 trains in cases within the same tunnel, tunnel ventilation system can be in the fire model under the condition of fire ventilation; Test the tunnel under the condition of fire smoke exhaust effect of smoke extraction system, and the tunnel fire smoke exhaust wind speed test results are analyzed, and put forward the relevant conclusions, the article offer reference for engineering design and management.
