摘要
在分析传统公路隧道洞外亮度L20(S)测算方法不足的基础上,介绍一种基于数码技术的公路隧道洞外亮度L20(S)测试方法,使得大规模、高效率地实测公路隧道洞外亮度L20(S)成为可能。采用上述方法和手段对金丽温、两龙高速公路隧道洞口光环境进行实测,提出浙西南山区高速公路隧道洞外亮度L20(S)建议值,可供高速公路隧道照明系统节能运营及改造设计时参考。基于环境景观理论,提出符合"环境友好型"山区高速公路隧道设计理念的接近段减光措施。研究成果具有较好的经济效益、社会效益和生态效益,可在实际工程中全面推广应用。
The shortcomings for traditional measurement method of L20 （S）are analyzed, and a novel measurement method of L20 （S）based digital technology is introduced,making large-scale and high efficiency measurement is possible. Using this method and means test lighting environment of road tunnels in Jin- Li-Wen and Liang-Long Expressway,and recommended value of L20 （S）in southwest mountainous areas of Zhejiang Province is put forward,it can provide the reference for energy-saving operation and transformation design of road tunnel lighting system. Based on landscape theory, measures are also proposed to reduce light for access zone that consistent with ＂environmentally friendly＂designing philosophy of expressway tunnel in mountainous areas. This research result has the better economic and social and ecological benefits that can be fully application in practical engineering.
