摘要： 结合国际照明协会推荐的一般天空亮度模型，基于DIALux照明计算软件对公路隧道入口段照明环境进行室内仿真，模拟了在全晴天、全阴天两种天空类型下，3种不同反射率（0.75、0.80、0.85）的反光材料，在4种布设高度(2.0、2.5、3.0、3.5 m）和两种布灯方式（中间及交错布灯）情况下洞口照明工况，研究反光材料在公路隧道入口段侧壁对隧道内路面平均亮度和亮度均匀度的影响，并选取实际能效值，表征反光材料布设方法对公路隧道照明节能效果的影响。结果表明：公路隧道入口段路面照度指标随侧壁反光材料反射率和布设高度的提高而增大；交错布灯对应的路面平均照度值远高于中间布灯所对应的路面平均照度值；洞外自然光的亮度越大，侧壁反光材料对洞口照明质量的提升效果越明显；反光材料布设在隧道侧壁的单位长度能效比受洞外亮度影响较大。

Abstract: Based on the general sky luminance model recommended by the International Lighting Association and the DIALux lighting calculation software, the indoor lighting environment of threshold zone of highway tunnel was simulated. Lighting conditions in threshold zone of highway tunnel of 3 kinds of reflective materials with different reflective nate (0.75,0.80,0.85) under different sky types(sunny day, cloudy day) and lamp layout modes( intermediate and staggered lamp layout) were simulated, with 4 kinds of layout heights (2.0,2.5,3.0,3.5). The influence of different layout methods of reflective materials at the side-wall of the highway tunnel threshold zones on the average brightness and brightness uniformity of road surface in highway tunnel was researched. And actual energy efficiency value was chosen to characterize the influence of laying methods of reflective materials on energy saving effect of highway tunnel lighting. The results show that: the illuminance of road surface in the threshold zone of the highway tunnel increases with the increase of the reflectivity of the side-wall reflecting material and the height of the layout; the average illumination value corresponding to staggered lamp layout is much higher than that corresponding to intermediate lamp layout; the greater the luminance of the natural light outside the tunnel, the more obvious the improvement effect of side-wall reflective material on the lighting quality of the tunnel threshold zone; the energy efficiency ratio per unit length of the reflective material laid on the side-wall of the tunnel is greatly affected by the brightness outside the tunnel.

Key words: tunnel engineering, tunnel threshold zone, energy saving of lighting, indoor simulation, side-wall reflective material, actual energy efficiency value
