摘　　要：公路隧道是我国交通运输工程重要的基础设施,隧道光环境的照明质量会极大地影响行车安全。而侧壁作为隧道光环境的关键组成部分,其表面污染程度和材料的反射特征将会影响隧道内光谱的分布特征,导致隧道光环境照明质量下降。因此,本文基于隧道内污染物对隧道侧壁的污染,研究了公路隧道侧壁污染对隧道内反射光谱的变化规律及其机理。首先将试板放置于实体隧道获取侧壁污染情况,然后将试板放入1∶10仿真隧道模型中,仿真真实的隧道光环境,通过仪器测量不同侧壁污染程度下隧道光环境的照明参数;最后,根据得到的实验数据分析其变化规律。研究发现,在经过6个周期的污染之后,侧壁试板表面特征发生较大的变化,但反射光谱均保持与光源灯具相同的双峰特征;隧道内反射光谱的S/P值下降率达到19.8%~20.9%,光环境的色温下降率达到13.5%~13.7%,研究结果为隧道光环境的运营和维护提供了科学依据。As an important infrastructure of transportation engineering in China,the lighting quality of tunnel light environment will greatly affect traffic safety.The sidewall is a key component of the tunnel light environment.The degree of surface pollution and the reflection characteristics of the material will affect the distribution characteristics of the spectrum in the tunnel,resulting in a decrease in the lighting quality of the tunnel light environment.Therefore,based on the pollution of pollutants in the tunnel to the side wall of the tunnel,this paper studies the variation law and mechanism of the reflection spectrum in the tunnel caused by the pollution of the side wall of the highway tunnel.Firstly,the test plate is placed in the solid tunnel to obtain the sidewall pollution,and then the test plate is placed in the 1∶10 simulation tunnel model to simulate the real tunnel light environment,and the lighting parameters of the tunnel light environment under different sidewall pollution levels are measured by the instrument.Finally,the change rule is analyzed according to the experimental data.The study found that after six cycles of pollution,the surface characteristics of the side wall test panel changed greatly,but the reflection spectrum maintained the same bimodal characteristics as the light source lamps;the S/P value of the reflection spectrum in the tunnel decreases by 21.6%~24.2%,and the color temperature of the light environment decreases by 14.2%~14.5%.The research results provide a scientific basis for the operation and maintenance of the tunnel light environment.
