| 摘 要： | 火区节流效应在公路隧道火灾过程中是一个典型的现象,研究公路隧道火灾的节流效应及其影响因素,对于火灾的正确模拟、判断灾情的发展、指导救援,都具有重要的意义.借助大尺寸火灾模型试验,深入研究了节流效应与通风风速、火灾规模之间的关系.试验隧道内径1.8 m,长度100 m,试验数据采集系统采用世界领先水平的有效支持分布式控制和实时控制的串行通信网络——CAN现场总线系统.并对火区节流效应进行了理论分析计算,将理论公式计算结果与试验结果进行比较,所得结果相吻合,证明了理论公式的正确性.

| Abstract: | Fire district throttling effect has always been a typical phenomenon in road tunnel fire.Researching the throttling effect of road tunnel fire and its modifying factors is vitally important to properly stimulate fire,analyze the development of disaster and guide rescue work.By means of large-scale fire model test,the relationship among throttling effect,ventilation speed and fire's scale has been deeply studied.The pilot tunnel's interior diameter is 1.8 m and it is 100m long.Taking CAN which reaches the wo... |
