| 摘 要： | 文章针对（特）长隧道的隧道内部与隧道外部的光线一般反差较大,驾驶员在隧道进出口处容易产生＂黑洞＂和＂白洞＂效应问题,结合公路隧道设计规范、公路隧道通风照明设计规范,通过分析隧道进出口处的特殊路段,确定隧道进出口过渡段的长度及隧道进出口过渡段的分布,并提出了相关的建议。

| Abstract: | The difference of light-ray between inner tunnel and outer tunnel is huge for extra long tunnel.It is easy for drivers to encounter black hole and white hole phenomenon.Combined with the tunnel design standard and lighting and ventilating requirement,the arti-cle determines the length of the changeover segment and its distribution through analysis,and provides related recommendation. |
