摘　　要：针对螺旋形隧道内驾驶员光环境特点,面向行车安全视觉生理需求,选择10个不同年龄段驾驶员开展其通行螺旋形和直线形两个隧道的心率测试试验,定量分析了驾驶员通过2种不同线形隧道加强段和基本段的心率变化和心率增长率。数据分析表明:在同等照明光环境下,驾驶员在两个隧道加强段行驶时心率数据总体变化不大,只有部分心率数据在螺旋形隧道要比直线型隧道偏高,说明驾驶员在2个隧道加强段行驶时驾驶员的心率变化较为舒缓,心率增长率最高不超过15%,因此,在隧道照明设计中螺旋形隧道加强段设计指标可按照相关标准规范进行设计,但要控制其光环境眩光和频闪效应。通过对LED照明光源的色温、频闪和眩光指标进行分析,优化了螺旋形隧道加强段和基本段LED照明灯具色温和亮度指标,提出了螺旋形隧道灯具布设方法。通过分析LED光源频闪效应机理和驾驶员眩光产生机理,采用模拟仿真软件,分析了隧道LED照明灯具配光曲线和纵横向出光量,提出了螺旋形隧道LED照明光环境频闪效应抑制方法,对隧道中间段隧道LED照明灯具纵横向配光曲线进行优化,降低纵向出光量,提高驾驶员纵向行车方向产生的眩光感,显著缓解隧道LED照明光环境的炫光效应。Considering the features of light environment around drivers in spiral tunnels and the visual physiological needs of driving safety, selecting 10 drivers of different age groups, the heart rate test in the spiral and straight tunnels are carries out. The heart rate variations and heart rate growth rates of the drivers passing through the reinforcement and basic sections of the spiral and straight tunnels are quantitatively analyzed. The data analysis result shows that(1) Under the same lighting environment, there is little change in heart rate data of the drivers in the reinforcement sections of the 2 tunnels, some heart rate data are higher in the spiral tunnel, only some heart rate data are higher in the spiral tunnel than those in the straight tunnel, indicating that the driver’s heart rate change is relatively relaxed when the driver is driving in the reinforcement sections of the 2 tunnels, and the maximum heart rate growth rate does not exceed 15%. Therefore, in the tunnel illumination design, the design indicators of the spiral tunnel reinforcement section can be in accordance with the relevant standards and specifications, but the glare and stroboscopic effect of the light environment should be controlled. Through analyzing the color temperature, stroboscopic and glare indicators of the LED lighting source, the color temperature and brightness indicators of the LED lighting fixtures in the reinforcement and basic sections of the spiral tunnel are optimized, and the layout method of the spiral tunnel lighting fixtures is proposed. By analyzing the mechanism of strobe effect of LED light source and the mechanism of driver glare, by using simulation software, the light distribution curve and vertical and horizontal light output of LED lighting fixtures in the tunnel are analyzed, a method for suppressing the strobe effect of spiral tunnel LED lighting environment is proposed, the vertical and horizontal light distribution curves of the LED lighting fixtures in the tunnel middle section are optimized, which
