【摘要】：随着我国高速公路建设事业的不断发展，公路隧道数量日趋增多然而，不断增长的交通流量车流密度以及设计车速给高速公路的行车安全造成很大威胁特别在公路隧道路段，由于背景亮度较低，人工照明所产生的强对比度会在驾驶员眼中形成眩光影响，这就对驾驶员的视觉功能造成障碍研究公路隧道照明中眩光对驾驶员视觉功能的影响可以为改进公路隧道照明提供可靠的参考依据本文主要针对以下几个方面作了研究：（1）基于公路隧道照明环境，分析了眩光对驾驶员视觉功能的影响机理眩光作用于人眼，在人眼中形成等效光幕亮度，进而影响驾驶员的视觉判断能力（2）在公路隧道照明环境下，对眩光产生的影响因素进行分析，得出公路隧道中眩光影响等级G及眩光恢复时间T的计算方法（3）利用Autodesk Ecotect Analysis软件对隧道照明进行模拟仿真，获得公路隧道照明中多种灯具布设情况下的眩光分析数据通过对仿真数据的定量分析，确定公路隧道中照明灯具对驾驶员的眩光影响范围（4）结合几何光学，分析公路隧道中眩光影响范围从灯具布设角度对减眩措施进行研究，，得出了有效的减眩灯具布设方法本文创新性的提出并分析了公路隧道人工照明环境下眩光对驾驶员视觉的影响，并针对眩光影响进行定量分析，为公路隧道照明设计提供了有效的参考依据，有助于进一步实现更安全更舒适的公路隧道照明
[Abstract]:With the continuous development of highway construction in China, the number of highway tunnels is increasing day by day. However, the increasing traffic flow density and design speed pose a great threat to the safety of highway, especially in highway tunnel sections. Because the background brightness is low, the strong contrast produced by artificial lighting will form glare effect in the driver's eyes. Study on the influence of glare on driver's Visual function in Highway Tunnel Lighting can provide reliable reference for improving Road Tunnel Lighting This paper mainly focuses on the following aspects: 1) based on the lighting environment of highway tunnel, the influence mechanism of glare on driver's visual function is analyzed. Glare acts on human eyes and forms equivalent luminance in human eyes, thus affecting the driver's visual judgement ability. 2) in the lighting environment of highway tunnel, the influencing factors of glare are analyzed, and the calculation method of glare influence grade G and glare recovery time T in highway tunnel is obtained. 3) using Autodesk Ecotect Analysis software to simulate tunnel lighting, the glare analysis data of various lamps and lanterns in highway tunnel lighting are obtained through quantitative analysis of simulation data. Determination of the influence range of Lighting Lighting on driver's glare in Highway Tunnel Combined with geometrical optics, this paper analyzes the influence of glare in highway tunnel and studies the dizziness reduction measures from the point of view of lighting layout, and obtains an effective method for the arrangement of dizzy-reducing lamps and lanterns. This paper puts forward and analyzes the influence of glare on driver's vision under artificial lighting environment of highway tunnel innovatively, and carries on the quantitative analysis to the glare influence, which provides the effective reference basis for the highway tunnel lighting design. Help to achieve safer and more comfortable road tunnel lighting
