自然光对公路短隧道照明环境的影响研究

Study on Influence of Natural Light on Lighting Environment of Expressway Short Tunnels

随着高速公路不断向山区延伸,修建的短隧道越来越多,但国内对短隧道自然光环境指标的量化研究却较少,导致其照明系统设计标准不统一,存在过渡设计或者亮度不足的情况。建立短隧道自然光照明环境模型,分析自然光影响下不同长度短隧道内的照明环境,为短隧道照明规范编制和照明系统设计提供借鉴。

With the rapid extension o f the expressway to the mountainous a re a, there are more and more short tunnels, but there is l i t t le quantitative research to natural l ig h t environmental indicators o f short tunnels in China, resu lt in g in many diffe re nt l ig h t in g system design standards, there may be excessive or inadequate l ight ing design. In this p a p e r, a l ig h t in g environment model o f short tun nel is established to analyze the l ight ing environment o f diffe re nt length short tunnels under the in flue nce o f natural l ig h t. This provides reference for short tun nel lig h t in g specification compilat ion and l ig h t in g system design.
