南京长江隧道火灾应急方案

以南京长江隧道为研究背景，分析隧道火灾可能带来的结构损伤、人员伤害及救援难点，在此基础上建立了应急响应流程。运用火灾动力学模拟软件PYROSIM建立隧道物理模型，计算分析火灾发生过程中风机风速对烟气蔓延速度、浓度和温度的影响，通过计算分析选择3．0m／s纵向通风作为临界风速，并结合分析结果提出了隧道火灾时人员疏散、车辆及装备救援以及现场救助的方法。

Fire Emergency Program for Nanjing Yangtze River Tunnel

Taking Nanjing Yangtze River tunnel as a research background, this paper analyzed potential structural damage, personal injury and rescue difficulty caused by fire disaster inside tunnel, and established an emergency response procedure. A physical model was built by using fire dynamics simulation software PYROSIM. This model could calculate the influences of ventilation speed on the smoke spread speed , smoke concentration and temperature during the fire. Then 3.0m/s longitudinal ventilation speed was chosen as the barrier speed. At last, this article expounded effective methods for people evacuation, vehicle and equipment protection and on-site rescue during a tunnel fire.
