隧道口减光设施对照明的影响研究

近年来,伴随着我国基础设施建设的不断推进,隧道里程不断增多,隧道照明系统的重要性日益突出,因此对隧道洞口驾驶员视觉特性、减光设施的特点及减光效果进行研究,具有重要的意义。本文通过对隧道洞口驾驶员的视觉特性进行研究,分别论述各种洞口减光设施的特点,并以南京扬子江路隧道、富贵山隧道、双龙街立交隧道的检测数据为基础,计算减光设施对洞口亮度的影响,以及隧道内加强照明的亮度需求的降低程度,进一步分析得出采用减光设施对照明设施建设的投资影响以及可节约的照明养护成本等。

Research on the Influence of Light-reducing Facilities of Tunnel Entrance on Illumination

In recent years,with the continuous advancement of infrastructure construction in China,the tunnel mileage is increasing,and the importance of tunnel lighting system is becoming increasingly prominent. Therefore,it is of great significance to study the visual characteristics of tunnel entrance drivers,the characteristics of light-reducing facilities and the effect of light-reducing. Through the study of the visual characteristics of tunnel entrance drivers,the characteristics of various tunnel entrance dimming facilities are discussed separately. Based on the detection data of Nanjing Yangzijiang Road Tunnel,Fuguishan Tunnel and Shuanglong Street Interchange Tunnel,the influence of dimming facilities on the brightness of tunnel entrance is calculated,and the brightness requirement of strengthening lighting in tunnel is also discussed. Further analysis shows that the use of dimming facilities has an impact on the investment of lighting facilities construction and can save the cost of lighting maintenance.
