A Study on Fire Fighting Safety System in Highway Tunnel
Yonglin An · Highway · 2008
The existent problems of tunnels which had occurred momentous fire are analyzed based on safety system analysis and combined with tunnel fire statistic.The principle block diagram and assessment indexes system of fire fighting safety system in tunnel are founded,and synthetic assessment function grounded on statistic by using multi-elements is established.The fire fighting safety systems of typical tunnels are evaluated reasonably,and grade criterion is formatted by its results.The assessment of the example in Xuefeng Mountain Tunnel shows that this method can well evaluate the status of fire fighting safety system in tunnel,so that the fire precautions may be accurately adopted,and the serious potential risk may be avoided.
