射流通风是公路隧道通风的主要方式，对于铁路隧道来说，射流通风技术是一项较新的通风技术。自1988年焦柳线牙己隧道(2528m)首次成功采用射流通风技术以来，该项技术也逐渐在铁路隧道中采用，并有了较快的发展。通过对巷道式通风和射流通风优劣的比较，确定大瑶山一号隧道进口段采用射流通风技术的巷道式通风方式，并给出了详细的通风方案，以及保证通风质量的相关措施。

Jet ventilation is one of the major ventilation modes for highway tunnels, while it is a somewhat new ventilation technology for railway tunnels. Since the first successful application of jet ventilation technology in Yaji tunnel (2528m long) on JiaoLiu railway in 1988, jet ventilation technology has been gradually used in railway tunnels and rapid progress has been made. On basis of comparison of the advantages/disadvantages of gallery ventilation and jet ventilation, it is determined that gallery ventilation incorporating jet ventilation technology is adopted for the entrance portion of No. 1 Dayaoshan tunnel. In the paper, detailed ventilation schemes are described and countermeasures to guarantee the ventilation effect are presented.
