摘　　要：为保障隧道安全运营,文章从驾驶员舒适性行车角度出发,采用室内试验的手段,以瞳孔面积变化速率和视觉震荡时间两项指标分析驾驶员明、暗适应时间,对已有照明适应曲线进行修正,并依据修正曲线对公路隧道照明设计标准进行修正,为隧道照明的安全性与舒适性设计提供理论支撑。结果表明:人眼最舒适色温为中色温(4000~5500 K),最舒适光源入射角度为20°;在入口段可通过修正亮度折减系数和安全停车视距对长度和亮度进行修正;在过渡段可通过修正入口段长度和亮度对过渡段长度和亮度进行修正;在出口段通过修正曲线提高出口段亮度时,需加长出口段长度,将出口段划分为3段,长度分别取6 s、4 s、4 s内行车距离。In order to ensure safe operation of the tunnel,the indoor test was performed from the perspective of drivers’comfortable driving to analyze the drivers’light and shade adaptation time by two indicators of pupil area change rate and visual concussion time,modify the existing lighting adaptation curve and correct the lighting design standard of highway tunnel according to the correction curve,so as to provide theoretical support for safety and comfort design of tunnel lighting.The results indicate that the most comfortable color temperature for human eyes is medium color temperature(4000~5500 K)and the most comfortable incidence angle of light source is 20°;in the entrance section,the length and brightness could be corrected by modifying the brightness reduction factor and the sight distance for safe parking;In the transition section,the length and brightness of the transition section could be corrected by modifying the length and brightness of the entrance section;when the brightness is improved in the exit section through the correction curve,it is necessary to lengthen the exit section and divide the exit section into three sections,of which the driving distance should be within 6 s,4 s and 4 s,respectively.
