摘　　要：为研究公路隧道侧壁反射率及涂装高度对隧道照明效果的影响,提升照明质量,降低隧道照明能耗,本文采用DIALux Evo照明设计软件分别计算了隧道侧壁反射率在30%~90%,涂装高度在2~7.5 m之间的49种隧道照明情况。研究表明:(1)隧道路面平均亮度与隧道侧壁反射率基本呈线性关系,提高隧道侧壁反射率能够提高隧道照明质量;(2)在双侧交错布灯时,隧道路面平均亮度与侧壁涂装高度基本呈线性关系,最佳涂装方式为全断面涂装,最有利于照明节能。本文为公路隧道运营及养护改造提供了一定指导依据。In order to study the influence of highway tunnel reflectance and coating height on tunnel lighting effect,improve lighting quality and reduce tunnel lighting energy consumption,the DIALux Evo lighting design software was used to calculate 49 tunnel lighting conditions with ttunnel sidewall reflectance of 30%~90% and coating height of 2 m~7.5 m respectively.Through the research,the following conclusions are drawn:(1)The average brightness of tunnel pavement is basically linear with the reflectivity of tunnel sidewall.Improving the reflectivity of tunnel sidewall can improve the lighting quality of the tunnel;(2)When the lamps are staggered on both sides,the average brightness of the tunnel pavement is basically linear with the coating height of the side wall.The best coating method is full-section coating,which is most conducive to lighting energy saving.This paper provides some guidance for the operation and maintenance of highway tunnels.
