摘要
我国现行的《公路隧道照明设计细则》对隧道照明灯具的布置形式进行了规定,包括中线、中线侧偏、两侧交错和两侧对称等形式,但未对灯具安装的高度和角度等具体位置进行相关要求,国际照明委员会及美国、日本等国家颁布的相关标准规范也存在同样的问题,而实际隧道工程中由于设计或者施工的原因,隧道灯具的照明光线往往未得到最大化的利用。本研究以广西百色至靖西高速公路安装LED照明灯具的那央隧道为例,利用DIAlux软件对灯具的不同安装高度和角度进行模拟试验,通过对得到的平均照度与均匀度数据进行对比分析,找出LED隧道灯的最佳安装位置。研究结论对优化公路隧道的照明设计和照明工程改造等理论、方法和实践具有参考价值。
The tunnel lighting layout pattern is prescribed in the current ＂Guidelines for Design of Lighting of Highway Tunnel＂（JTG/T D70/2-01-2014）including midline,midline cornering,staggered on both sides and both sides of the symmetry type,but there is no specific locations concerning to the height and angle of the lighting installation and other related requirements.Same problems exist in related standards posted by CIE,United States,Japan and other developed countries.The illumination light has not been maximized in its function due to the design or construction reasons in practice.In this study the Nayang Highway Tunnel which has been installed LED lighting in Guangxi is taken as example,DIAlux software is used to simulate different installation height and angle of the lighting luminaries,through analysis and comparisons to the obtained average illuminance and uniformity of the data to identify the best location for LED tunnel lights.The research conclusions have some theoretical and practical values for optimization of the illumination design and upgrading for highway tunnels.
