终南山隧道非充分动态照明环境特性分析

Analysis of Non-sufficient and Dynamic Lighting Environment Characteristics about Zhongnanshan Tunnel

以隧道内的静态照明值作为进行隧道光环境设计的依据,并不能真正体现出驾驶员在行车状态下的动态视觉照明环境。通过对6条隧道(单向)的照明状况调查发现,隧道的实测照度均较大程度低于《规范》设计照度,这种照明环境称之为非充分照明环境。通过对终南山隧道的实测动态照明数据进行数理统计得出:终南山隧道内实际动态照明强度明显偏小,处于显著的非充分照明状态;隧道入口段动态照明受速度影响小,中间段和出口段受行车速度影响明显;车内外照度差随着速度的增加有增大的趋势。

This foundation that a static lighting value is used as the basis in the tunnel can not truly reflect the dynamic visual lighting environment for the driver in the driving state. Through the lighting conditions has been investigated about six tunnels（ one-way）,have been found the measured illuminance is far below the specification design illuminance,and call be this non-sufficient lighting environment. By Zhongnanshan tunnel measured dynamic lighting data analysis,have been come to the conclusion that： Zhongnanshan tunnel exhibit significant non-fully illuminated state,because its actual dynamic lighting value is significantly less than static illumination value. Little influence by the speed of dynamic lighting of the tunnel entrance,and by the speed of dynamic lighting effect middle section and an outlet section of the tunnel is remarkable; illumination gap will increase as speed increases between inside and outside of the car.
