摘要
介绍城市地下交通隧道的特点及烟气控制方法。以某地下交通隧道为例,设置两种火灾场景:自然排烟、上游补风下游排烟,利用FDS模拟烟气控制效果。结果表明上游补风、下游排烟的烟气控制方式能够控制烟气的蔓延范围并且防止烟气回流,能够保证人员安全疏散。
Characteristics and smoke control method of under- ground transportation tunnel were introduced. Based on a un- derground transportation tunnel, two fire scenarios were made as natural smoke extraction, air replenishing in upstream and smoke extraction in downstream, and FDS was used to simulate effect of smoke control. The results showed that in condition of air replenishing in upstream and smoke extraction in down- stream,range of smoke spread was smaller and could prevent smoke reflux,which can ensure safety evacuation.
