摘　　要：目前国内外在海拔2400m以上无海拔修正系数的实测值。以高海拔特长公路隧道鹧鸪山隧道为依托,于2003-2005年对海拔400～4000m处烟雾海拔系数进行了现场测试,研究在营运隧道通风设计中烟雾海拔高度系数的合理取值,以对鹧鸪山隧道及类似高海拔地区公路隧道营运通风设计提供依据和参考。At present, no field-measured values are available in China and abroad for the modified altitude coefficient for areas with more than 2 400 m altitude. Regarding Zhegnshan tunnel, which is an extra-long highway tunnel with high altitude, the authors field-measured the smog altitude coefficient for areas with 400 m to 4 000 m altitude from 2003 to 2005 and studied on the reasonable value of smog altitude coefficient in the operation ventilation design of highway tunnels. The study can offer reliable basis and useful reference for the operation ventilation design of Zhegushan tunnel and some other similar high-altitude highway tunnels.
