一、铁路隧道防火铁路隧道发生的火灾,其原因与地上铁路发生火灾的原因相同,多数是由于设备故障,尤其是电气设备故障引起的。铁路隧道火灾的特点是,火源的温度高,燃烧物蔓延距离远,火势顺通风方向发展,火灾危及整个隧道的安全。火车运载易燃物时,这些危险急骤增加。实践证明,如果隧道内设安全门和备用的疏散走道,对人员疏散和灭火将是非常有益的。关于隧道火灾人员的疏散问题,1974年日本专家做过调查。其结果是:如果车厢起
First, the railway tunnel Fire railway tunnel fire, the reason and the ground railway fire the same reason, mostly due to equipment failure, especially caused by electrical equipment failure. The characteristics of the railway tunnel fire are that the temperature of the fire source is high, the spread of the combustion products is far, and the fire is prone to develop in the direction of the ventilation. The fire threatens the safety of the entire tunnel. These dangers have risen sharply as trains carry flammable materials. Practice has proved that if the tunnel with security doors and spare evacuation walkway, the evacuation of personnel and fire will be very useful. On the evacuation of tunnel fire crews, Japanese experts conducted a survey in 1974. The result is: if the car from
