摘　　要：针对城市隧道照明设计中洞外亮度获取困难、多参数相互影响等问题,提出一种基于数值模拟的城市隧道洞外亮度的计算方法。该方法基于DIALux4.13软件构建城市隧道模型,结合国际照明委员会CIE 88-2004规范推荐的环境简图法和不规则面积计算方法实现对洞外亮度L20(S)的数值模拟计算。基于该方法,系统研究了城市隧道环境各参数对洞外亮度的影响规律。结果表明:光气候分区对隧道洞外亮度有一定的影响,尤其对南洞口的影响较大;当洞口朝向位于东北、东南、西南、西北之间时,洞外亮度与角度近似呈线性关系;洞外亮度折减系数与光过渡长度基本都呈线性关系;在城市隧道设计中,应适当考虑纵坡对洞外亮度的影响。该工作可为城市隧道照明设计提供更为方便、快捷的技术支持。In order to solve the problems that it is difficult to obtain the adaptation luminance and the influence of the multiparameters in the design of the urban tunnel lighting, a method of the urban tunnel lighting based on the numerical simulation was presented. In this method, the lighting environment simulation of the adaptation luminance was carried out using the DIALux4.13 lighting calculation software, and combining with the environment sketch method given in the report of CIE 88-2004 of the International Lighting Commission, the adaption luminance L20(S) was calculated using a method of calculating irregular area. Based on the above method, the influences of the urban tunnel environmental factors on the adaptation luminance are studied. The results show that the climate zone has a certain influence on the adaptation luminance, and it has a more effect on the south entrance of the tunnel. When the entrance orientation is between northeast, southeast, southwest and northwest, the relationship between the luminance L20(S) and the angle is approximately linear. There is a linear relationship between the luminance reduction coefficient and the light transition section. In the design of the urban tunnel, the influence of the longitudinal slope on the adaptation luminance should be considered. It presents the more convenient and fast methods for the urban tunnel lighting design.
