【摘要】：随着我国高速公路的快速发展,公路隧道的数量和规模都进入了世界的前列,隧道照明能耗也逐年增加,照明已成为隧道运营的巨大负担。公路隧道中间段是隧道中最长的部分,且隧道越长,中间段也越长。隧道中间段所使用的照明灯具最多,其照明耗电量在总耗电量所占的比重最大,因此,降低隧道中间段的照明能耗将大大降低隧道照明总能耗。我国对隧道照明节能方面的研究主要集中在照明控制方面,在布灯参数优化方面相对较少。本文将从优化布灯参数方面对隧道中间段照明节能进行研究,在满足隧道照明基本要求的前提下,最大限度的降低能耗。根据公路隧道照明设计规范,以灯具安装高度、灯具纵向间距、灯具横向间距、灯具安装仰角和单灯功率为优化参数,以总功率最小为目标,以路面照度满足照明要求为约束条件,分别建立了隧道中间段采用中央布灯、两侧对称布灯、两侧交错布灯、拱顶侧偏布灯以及逆光布灯照明系统的参数优化模型。以江西九景高速公路雁列山隧道中间段为研究对象,选用LED灯,分别利用中央布灯、两侧对称布灯、两侧交错布灯、拱顶侧偏布灯以及逆光布灯照明参数优化模型,优化得出各布灯方式的最优布灯参数以及路面各计算点的照度,与《公路隧道照明设计细则》要求值比较可知,灯具在光衰30%以后路面照度和均匀度依然满足照明要求。比较了各布灯方式最优布灯参数下的照明总功率:对于单排布灯,中央布灯方式比拱顶侧偏布灯方式更节能;对于双排布灯,两侧对称布灯比两侧交错布灯更节能;各优化布灯方案均比原布灯方案和改造后的布灯方案有较大幅度的节能。利用Dialux软件建立了雁列山隧道的三维仿真模型,按照各布灯方式的优化布灯参数在仿真模型中设计了LED照明系统并进行了仿真实验,仿真值和优化计算值比较接近,路面最小照度最大误差3%,且基本都满足照明规范要求,证明了优化模型的正确性。仿真研究了灯具安装高度、纵向安装间距、横向安装间距和安装仰角单一参数变化(其它参数保持不变)对隧道路面照明效果的影响。对隧道中间段各布灯方式的优化布灯方案进行了经济性分析,估算了灯具在使用100000h后的总费用,与原布灯方案和改造后的布灯方案进行了总费用比较,可知各优化布灯方案均比原布灯方案和改造后的布灯方案大大节省了成本,经济效益更好。
[Abstract]:With the rapid development of highway in China, the number and scale of highway tunnels have entered the forefront of the world, and the energy consumption of tunnel lighting is increasing year by year. Lighting has become a huge burden of tunnel operation. The middle section of highway tunnel is the longest part of the tunnel, and the longer the tunnel, the longer the middle section. Its lighting power consumption in the proportion of total electricity consumption is the largest, therefore. Reducing the lighting energy consumption in the middle section of the tunnel will greatly reduce the total energy consumption of the tunnel lighting. The research on energy saving of tunnel lighting in China is mainly focused on lighting control. The optimization of lighting parameters is relatively few. This paper will optimize the lighting parameters of the middle section of the tunnel lighting energy saving, under the premise of meeting the basic requirements of tunnel lighting. According to the design code of highway tunnel lighting, the optimal parameters are the installation height of lamps, the longitudinal spacing of lamps, the horizontal spacing of lamps, the elevation angle of lamp installation and the power of single lamp. Taking the minimum total power as the target and the illumination of the road surface satisfying the lighting requirements as the constraint conditions, the middle section of the tunnel adopts the central light, the symmetrical light on both sides and the staggered light on the two sides. The parameter optimization model of the lighting system of the dome side bias lamp and the reverse light distribution lamp. Taking the middle section of Yanlieshan Tunnel of Jiujing Expressway in Jiangxi Province as the research object, the LED lamp is selected, and the central distribution lamp and the symmetrical light distribution on both sides are used respectively. The optimization model of the lighting parameters of the two side staggered lamp, the dome side skew lamp and the reverse light distribution lamp is obtained, and the optimal light distribution parameters of each light distribution mode and the illuminance of each calculation point on the road surface are obtained. Compared with the requirements of Highway Tunnel Lighting Design rules. After 30% light loss, the illumination and evenness of the road surface still meet the lighting requirements. The total power of lighting under the optimal light distribution parameters of each light distribution mode is compared: for single-row lamps. The central light distribution mode is more energy saving than the dome side bias light distribution mode; For the double arrangement lamp, the symmetrical cloth lamp on both sides is more energy saving than the staggered light on both sides. The optimized light distribution scheme is more energy saving than the original lamp layout scheme and the modified lamp layout scheme. The 3D simulation model of Yan-lieshan Tunnel is established by using Dialux software. The LED lighting system is designed in the simulation model according to the optimized light distribution parameters of each light distribution mode and the simulation experiment is carried out. The simulation value is close to the optimized calculation value and the maximum error of the minimum illuminance of road surface is 3%. And basically meet the requirements of the lighting code, proved the correctness of the optimization model. Simulation of the lamp installation height, longitudinal installation distance. The influence of the single parameter change of transverse installation distance and elevation angle (other parameters remain unchanged) on the lighting effect of tunnel pavement is discussed. The economic analysis is carried out on the optimized light distribution scheme of each light distribution mode in the middle section of the tunnel. The total cost of lamps after using 1000 hours was estimated, and compared with the original lamp layout scheme and the modified lamp layout scheme. It can be seen that all the optimized lamp layout schemes have greatly saved the cost and better economic benefit compared with the original lamp layout scheme and the modified lamp layout scheme.
