自然光对公路短隧道照明环境的影响研究

摘要

With the rapid extension of the expressway to the mountainous area, there are more and more short tunnels, but there is little quantitative research to natural light environmental indicators of short tunnels in China, resulting in many different lighting system design standards, there may be excessive or inadequate lighting design. In this paper, a lighting environment model of short tunnel is established to analyze the lighting environment of different length short tunnels under the influence of natural light. This provides reference for short tunnel lighting specification compilation and lighting system design.%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.
