隧道通风分施工通风与运营通风,这里讲的是运营通风。隧道通风的任务与隧道通风所能解决的问题似乎要从对“隧道通风”的认识谈起。 (一)隧道烟气问题与隧道通风问题火车通过隧道,机车排放的烟气不能很快滑散,危及人身健康,甚至发生急性中毒事故,这是隧道烟气问题,其统称应为部颁《铁路工程技术规范》中所称的“隧道内有害气体的防治问题”,为简便起见,这里暂沿用通俗的“隧道烟气”一词。对于隧道烟气为害的问题,往往被视为通风不良所引起,于是常有人把此问题列为隧道通风问题。实际上这样把“隧道烟气问题”与“隧道通风 Ventilation and ventilation of the tunnel construction Ventilation and operation, here is the operational ventilation. The problems that can be solved by the task of tunnel ventilation and tunnel ventilation seem to start with the understanding of “tunnel ventilation.” (1) Tunnel Flue Gas Problems and Tunnel Ventilation Problems The train passes through a tunnel and the flue gas emitted by locomotives can not slip away quickly, endangering people’s health or even causing an acute poisoning accident. This is a tunnel flue gas problem and should be collectively referred to as “ Railway Engineering Specifications ”referred to as“ the prevention and treatment of harmful gases in the tunnel ”, for the sake of simplicity, temporarily here to use the popular“ tunnel flue gas ”. The problem of harmful flue gas from tunnels is often regarded as caused by poor ventilation. Therefore, it is often cited as a problem of tunnel ventilation. In fact this “tunnel flue gas problem” and "tunnel ventilation
