摘要(Abstract):

隧道洞外景物亮度是隧道照明设计最重要的基准参数,合理的隧道洞外景物亮度值的选择既能保证隧道照明的安全性又能保证隧道照明的经济性。我国现行隧道照明设计标准中给出的隧道洞外景物亮度的标准值,是直接选用CIE隧道照明指南中给出的建议值。实际上,由于各个地区的光环境的差异以及隧道洞外景物的表面材料反射特征的差异,必然会导致隧道洞外景物亮度的差异。因此,本文在大量的调研基础上,结合已有的最新的光气候研究成果,提出了用光气候理论研究隧道洞外景物亮度新的理论和方法。
The luminance at tunnel portals is the most important benchmark parameter in tunnel lighting design.A proper selection of the value of the luminance at tunnel portals can guarantee both the security and economics of tunnel lighting.At present,the suggested standard value by CIE is directly used as the standard value of this index in our country's standard for tunnel lighting design.In fact,differences in luminous environments of different areas and differences in reflection characteristics of surface materials of tunnel portals inevitably lead to differences in luminance at tunnel portals.Therefore,integrated with existent latest research achievements of luminous climate,this paper develops a new theory and methodology to apply luminous climate theory to research luminance at tunnel portals based on a plenty of investigations.
