摘要
地铁车站及地铁列车为人流密集的公众聚集场所,一旦发生火灾事故伤亡损失往往非常惨重,因此深入开展地铁火灾安全的研究有助于地铁安全管理工作。在合理分析地铁站台和列车火灾荷载的基础上,采用数值模拟方法对活塞风情况下地铁区间隧道火灾问题进行了模拟计算和分析,研究了在活塞风影响下的烟气蔓延规律和温度分布情况,其结果有助于提高地铁车站的运营的安全管理和发生火灾后的疏散指挥能力。
Subway platform and sub-train are densely populated venues, and casualty would be disastrous if fire happens in these places. Thus it is of great importance for subway safety management to study the sub-train fire. Based on the analysis of fire load of subway platform and sub-train and by using numerical simulation, the characteristics of subway train fire under the effect of piston wind was studied. The rule of fire smoke movement and the distribution of fire smoke temperature were investigated. The conclusion is useful for the operation of safe management and evacuation in fire.
