摘　　要：研究目的:目前国内高海拔地区(海拔>3 000 m)隧道内燃牵引运营通风设计中,有害气体容许浓度没有相应的规范可参照。通过国内外高、低海拔地区CO、NO2最高容许浓度的比较,国内外隧道运营通风与环境控制标准检索、分析,提出高海拔隧道内燃牵引运营通风控制标准建议值。研究结论:国内相关规范(标准)规定的有害气体最高容许浓度比国外发达国家的标准要求高。初步建议高海拔运营隧道内空气中内燃机车废气的容许浓度:NOx(以NO2计):工作日内平均容许浓度为10 mg/m3,工作日内任何一次30 min内接触废气的平均浓度不超过30 mg/m3。CO:工作日内平均容许浓度为30 mg/m3,工作日内任何一次30 min内接触废气的平均浓度不超过90 mg/m3。Research purposes： In order to solve the problem of standards about allowable concentration of harmful emission gases to operation ventilation of diesel traction in high- altitude（ 〉 3 000 m）tunnel. Based on the comparison results of operation ventilation standards and allowable concentrations of harmful emission gases, CO, NO2 control of the maximum allowable concentration, the suggestion standards of operation ventilation control of diesel traction in high altitude tunnel is presented.Research conclusions：The national standards is more stringent than the developed countrie＇ s. The suggestion standards of operation ventilation control of diesel traction in high altitude tunnel are that time weightd average （ TWA ） of NOx （nitragen dioxide level ） is 10 mg/m3 in workday, short term（30 min）exposure limit of NOx ≤30 mg/m3. TWA of CO is 30 mg/m3 in workday, short term（30 min）exposure limit of CO ≤90 mg/m3.
