摘要

以某公铁同层桥梁为背景,以道路失能眩光造成的阈值增量为评价指标,基于DIALux光学仿真分析软件,结合现场试验进行公铁同层桥梁防眩设施研究,并从屏障结构和列车光源2个层面开展影响屏障防眩效果的参数分析.结果表明:屏障高度和遮光角需大于某一阈值才能满足防眩要求,本案例为3.0m和12°;当屏障开孔率较大或者光源灯柱角度和光通量较大时,需要进一步校核眩光指标,以免其漏光严重;灯柱角度和屏障材料基本不影响眩光水平;影响眩光水平的主要因素为屏障高度、遮光角和列车灯光通量.

Abstract

Taking a road-rail same-story bridge as the background,this paper carries out the optical simulation analysis based on DIALux by making the threshold increment of road disability glare as the glare evaluation index,then the anti-glare research on the anti-glare facilities is operated combined with field tests.Furthermore,parameter analysis is done to research the influence factors of anti-glare effect through barrier's structural design and train front light.Results show that the barrier height and shielding angle need to be greater than a certain threshold in order to meet the anti-glare requirements,in this case,they are 3.0 m and 12°.When the aperture ratio of the barrier increases or the beam angle and luminous flux of the luminaire are larger,the glare indicator needs to be further calibrated to avoid serious light leakage.The beam angle of the luminaire and the type of barrier material have essentially no effect on the level of glare.Main factors influencing glare level are barrier height、shielding angle and train front light's luminous flux.
