摘　　要：通过对大相岭泥巴山特长公路隧道施工通风技术的研究,隧道施工前期采用压入式通风,后期采用巷道式通风,利用射流风机和轴流风机的有效组合,不断对巷道式通风方式进行优化,成功地解决了轴流风机和射流风机的选型、布置以及通风管理等问题,使洞内空气质量的各项指标均达到了国家环卫标准,实现了内燃作业和无轨运输,取得良好的经济效益和社会效益,可供类似工程借鉴。Through study on the ventilation technologies in the tunnel construction of Niba Mount.Extra-long road in Daxiangling,forced ventilation was used at the earlier stage of tunnel construction,and gallery ventilation was adopted at the later stage,an effective combination of the jet fan and the axial-flow fan was made use of,and the gallery ventilation mode was optimized constantly,which successfully solved the problems such as type selection of the jet fan and the axial-flow fan,their layout and ventilation management.Therefore,every index of the air quality inside the tunnel reaches the national environmental hygiene standards,internal combustion working and trackless transportation are realized,achieving good economic and social benefits,which can be reference to similar engineering.
