摘要
火灾发生时隧道内烟气流的扩散规律对火灾救援至关重要。以张涿高速公路分水岭特长隧道为背景,采用计算流体动力学方法,对隧道火灾烟气流扩散进行数值模拟,总结了火灾工况下的烟气扩散规律,据此提出了相应的公路隧道火灾救援对策。
The law of fume flow distribution is crucial to the rescue work during tunnel operation period. Taking Fenshuiling extra-long tunnel at Zhangjiakou-Zhuozhou Expressway as an instance, the computer fluid dynamics (CFD) method is adopted to simulate the fume flow spreading process and the fume flow diffusion rule is summarized in detail. Therefore, the rescue countermeasures are presented on basis of these analysis results during fire hazard in the article.
