摘　　要：为了降低隧道运营期间的能耗与工程造价,利用视觉适应性曲线分别对是否架设隧道遮光棚的两种不同情况建立了单个隧道、毗邻隧道的亮度数学模型和所需光通量差值模型,基于差值模型计算了二者之间照明功率的差值。考虑遮光棚建设费用及后续运营维护费用,分析设置遮光棚的照明经济性,并提出了设置遮光棚的条件:仅考虑遮光棚建设费用,当节省下来的灯具光通量的费用大于等于建设费用时,设立遮光棚更具照明经济性;若考虑遮光棚建设与后续维护费用,当节省下来的灯具光通量费用、电费以及灯具维护费总和大于等于遮光棚的建设费用与维护费用时,设立遮光棚更具照明经济性。In order to reduce the energy consumption and project cost during the tunnel operation,the visual adaptation curve was used to determine whether or not to erect the tunnel shading shed.The luminance mathematical model and the required luminous flux difference model of single tunnel and adjacent tunnel were established,and the difference of lighting power between them was calculated based on the difference model.Taking the construction cost of the shading shed and its subsequent operation and maintenance cost into account,the lighting economy of setting shading shed was analyzed and the conditions of setting shading shed are proposed.The research shows that if only the construction cost of shading shed is considered,when the saved luminous flux cost of lamps is greater than or equal to the construction cost,the establishment of shading shed is more lighting economic;if the construction and subsequent maintenance costs of the shading shed are considered,when the sum of the saved luminous flux cost,electricity cost and maintenance cost of the lamps is greater than or equal to the construction cost and maintenance cost of the shading shed,the establishment of the shading shed is more lighting economic.
