摘要
以乌东德水电站右岸对外交通老鹰窝特长隧道为例,研究射流风机联动方式、施工支洞作为逃生通道对火灾工况下延期流动的影响。采用火灾网络通风的计算方法研究4个防火分区分别发生火灾时隧道洞内空气流动规律及对交通、防火等的影响,得出各工况下防止烟气逆流的通风排烟方式。
Taking the Laoyingwo extra-long tunnel on the right bank of Wudongde hydropower station as an example, the influence of jet fan linkage mode and construction branch tunnel as escape passage on delayed flow under fire condition was studied. Using the calculation method of fire network ventilation, the air flow law in tunnel and its influence on traffic and fire prevention of fires in four fire prevention zones were studied respectively. The ventilation and smoke exhaust modes to prevent the reverse flow of smoke under different working conditions were obtained.
