【摘要】：随着公路隧道的不断修建,隧道运营消耗的能源问题越来越受到专家学者的关注。对于公路隧道入口段照明设计而言,洞外亮度值是一个关键性参数。驾驶员从较亮的洞外环境到较暗的洞内环境时,通常会产生"黑洞效应",为此入口段亮度必须提高到一定水平,这必定会消耗巨大的电能,因此进行隧道洞外减光是节约隧道照明电能的有效途径。在已运用的隧道洞外减光结构物的基础上,提出了一种新型的绿色减光形式。通过数值计算,分析结构物顶部透光率对棚下路面照明效果的影响,得到当顶部透光率为2%~3%时所达到的减光效果最好。研究结论对于今后公路隧道洞外减光设计具有重要的参考价值。
[Abstract]:With the continuous construction of highway tunnel, the energy consumption of tunnel operation has been paid more and more attention by experts and scholars. The luminance value outside the hole is a key parameter. When the driver moves from the brighter outside environment to the darker hole environment, it usually produces a "black hole effect". For this reason, the luminance of the entrance must be raised to a certain level, which is bound to consume a huge amount of electric energy. Therefore, reducing the light outside the tunnel is an effective way to save the lighting energy of the tunnel. On the basis of the light reducing structure used outside the tunnel, a new type of green light reducing form is proposed. By analyzing the influence of the top light transmittance of the structure on the lighting effect of the pavement under the shed, it is concluded that the best light reducing effect can be achieved when the top light transmittance is 2 ~ 3. The conclusion of the study has important reference value for the future light reduction design of the highway tunnel outside the tunnel.
