摘　　要：隧道入口的长度和亮度与交通安全密切相关,根据CIE88理论推导出了满足行车安全的隧道入口遮光棚长度、亮度的计算公式,为遮光棚的设计提供了理论依据。通过案例分析表明,遮光棚的应用与传统电光照明相比不仅具有节能减排作用,还可有效降低工程造价,具有较好的经济优势。The length and brightness of tunnel entrance are closely related to traffic safety.According to the CIE88 theory,this paper deduces the calculation formula of length and brightness of shading sheds at tunnel entrance based on traffic safety,which provides a theoretical basis for the design of shading sheds.The case study shows that the application of shading sheds can effectively reduce the project cost.Compared with traditional lighting,it not only has the effect of energy saving and emission reduction,but also has better economic advantages.
