摘要: 利用室内缩尺模型试验结果,分析不同光通量的前置光源对隧道内小目标可见度,亮度,亮度均匀度的影响,研究前照灯影响小目标可见度的作用机理;同时利用Dialux来模拟隧道内前照灯对路面照明质量的影响。研究表明:前照灯能够明显增大所在车道正前方的小目标亮度,对路面平均亮度、均匀度有微小的影响,但会降低路面的小目标可见度,这种影响限定在其所直接照射范围以内;前照灯的光通量越大,其对小目标可见度的削弱就越明显,较高的路面亮度和有较好反射率的侧壁可以改善这种影响。

Abstract: The results of the laboratory scale model test were used to analyze the influence of the front light source with different luminous flux on the visibility, luminance and luminance uniformity of the small target in the tunnel. The mechanism of the effect of headlights on the visibility of small targets was researched. Meanwhile, Dialux was used to simulate the influence of the headlights on the quality of tunnel pavement lighting. Research results show that: vehicle headlights can highly improve the luminance of small targets but only have a little influence on road luminance and luminance uniformity. It will reduce the small target visibility of the road, which is limited to the direct range of its exposure. The bigger luminous flux of the headlamp is, the more seriously the small target visibility will be weakened; higher road luminance and sidewall with better reflectivity can improve the small target visibility under headlights.

Key words: tunnel engineering, vehicle headlights, small target visibility, model experiment, evaluation index for tunnel lighting
