【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。

1概述随着我国交通建设事业的迅猛发展,公路隧道建设进入了一个崭新的发展时期,高海拔地区出现了一大批拟建或在建的特长公路隧道。仅以四川为例,就有日尔郎山隧道(长1.6 km,海拔3 509 m)、巴朗山隧道(长5.7 km,海拔3 900~4 100 m)、拉纳山隧道(长3.45 km,海拔3 044~3 049 m)
