摘　　要：本文研究了在隧道墙面不同高度设置不同反射率涂料对路面照度的关系,利用DIALux软件模拟隧道两侧墙面不同高度和不同反射率涂料对隧道路面照度的影响,结果表明,隧道墙面涂料涂设高度在2.5 m时对路面照明光环境的贡献率最高,经济效益大;采用反射率不小于0.7的漫反射墙面涂料,同时在隧道壁两侧设置颜色较深、高1.2 m、宽15~20 cm、间距30~40 cm的腰带线,不仅能够能起到行车诱导的作用,还可改善驾驶员视觉余光的单调性。This article studies the relationship between setting different reflectivity coatings at different heights of tunnel walls and road surface illumination.DIALux software is used to simulate the impact of different heights and reflectivity coatings on tunnel road surface illumination on both sides of the tunnel walls.The results show that when the height of tunnel wall coating is 2.5 meters,the contribution rate to the road surface lighting environment is the highest,and the economic benefits are significant;Diffuse reflective wall coating with reflectivity not less than 0.7 shall be adopted,and belt lines with deep color,1.2 m high,15~20 cm wide and 30~40 cm spacing shall be set on both sides of the tunnel wall,which can not only play the role of driving guidance,but also improve the monotonicity of the driver's visual residual light.
