摘要： 针对国内现行规范JTG/T D70/2—01—2014《公路隧道照明设计细则》与国际照明委员会CIE对于隧道入口段亮度计算方法的差异，推导了20°视野的等效光幕亮度计算方法。以重庆双山隧道为例，计算了不同天空环境下20°和56.8°视野的察觉对比度法入口段亮度，与规范设计值进行比较。研究结果表明：察觉对比度法考虑的视野范围更大，并且更多的考虑了周围景物环境、大气以及汽车挡风玻璃的综合作用对驾驶员视觉特性等生物因素的影响，计算结果较规范值偏大；采用逆光照明的察觉对比度法计算结果比采用对称照明时小52%左右，采用逆光照明能更好的减小隧道照明能耗；天空环境对隧道入口段亮度影响显著，入口段照明需根据天空类型进行分级。

Abstract: Aiming at the differences between the current domestic standard (code for Design of Road Tunnel: JTG/T D70/2—01—2014) and CIEs calculation method for the luminance in the threshold zone, the calculation method of the 20° equivalent veiling luminance was deduced, taking Chongqing Shuangshan tunnel as an example. The luminance in the threshold zone of the 20° and 56.8° field of view in different sky environments was calculated by the perceived contrast method, and compared with the normative design value. The research results show that: the perceived contrast method considers a larger field of view, and more consideration is given to the integrated influence of the surrounding scene environment, the atmosphere and the windshield of the car on the biological factors such as the drivers visual characteristics. Therefore, its calculation result is higher than the normative value. The result of the perceived contrast method using backlight illumination is about 52% smaller than that of symmetrical illumination. Backlighting can reduce the energy consumption of tunnel lighting. The sky environment has a significant influence on the luminance in the threshold zone. The luminance in the threshold zone needs to be ranked based on the sky type.

Key words: tunnel engineering, perceived contrast method, K-value method, luminance in the threshold zone, tunnel lighting
