摘要
以公路隧道发光涂料为研究对象，对数值仿真模型进行研究，建立起以路面平均亮度作为关键评价指标的公路隧道发光涂料仿真计算模型。采用三维数值仿真方法，对隧道内墙壁发光涂料铺设范围以两侧3米高为基准向上铺设时的效果进行研究，分别模拟计算了不铺设和铺设至两侧2m、3m、4．54m、5．71m、6．5m、7m高度及全截面这8种情况。通过汇总分析隧道路面平均亮度及能效值等关键参数，得到隧道内平均亮度变化范围在8．7～12．1ed／m。，能效值随铺设范围增大而减小，在墙壁两侧3m高度范围内铺设时的经济技术性最优。
This paper takes road tunnel luminous coatings for the study, conducts research on numerical simulation model, in order to establish a road tunnel simulation model of luminous coatings which takes the average luminance of road surface as key evaluation. Use three-dimensional numerical simulation methodto research the effect of different laying ranges of luminous coatings which start growing with 3m height on both sides of tunnel walls, and simulate seven cases that including laying range of none, 2m, 3m, 4.54m, 5.71m, 6.5m, 7m and all section. By summarizing and analyzing the key parameters such as average luminance of road surface and value of energy efficiency, a result can be calculated that the variation of average luminance of road surface in tunnel range from 8.7cd/m2 to 12. lcd/m2 , value of energy efficiency decreases with increasing range of laying, and the economical efficiency is highest in the condition of laying range 3m.
