摘　　要：长大隧道施工中通风排烟是不容忽视的重要问题。岩山隧道采用长4 km的平导辅助正洞施工,平导多次通过横通道进入正洞施工,平导独头施工通风距离长达5.4 km,文章介绍了该隧道施工中采用高风压、大风量通风机、大直径风管进行多种形式的通风,以及加强施工通风管理等经验,较好地解决了长距离通风,有效地提高了工作效率,加快了施工进度。平导施工通风经验可供类似工程参考。Changda tunnel construction ventilation is the serious problemthat nots allowto ignore.Rock tunnel with long 4 kmflat guide auxiliary hole construction,flat guide repeatedly through the passageway into the hole construction,blind construction ventilation by flat over a distance of up to 5.4 km,this article introduces the tunnel construction in the high wind pressure,wind volume of fan,big diameter air tube to carry out various forms of ventilation,and strengthen the construction of ventilation management experience,can solve the long distance ventilation,and effectively improves the working efficiency,speed up the construction progress.
