摘要:根据失能型眩光的环境光强对比度原理，提出了基于三维空间关系模型的失能眩光分析流程。以国内某斜拉桁架桥下层公路铁路同层布置为工程背景进行了案例分析。当公铁近距离布置不采取防眩措施时，铁路列车前照灯产生的眩光效应严重，远超相关规范的阈值要求。最后，提出了可装配、立体化的防眩策略，并根据案例给出具体的防眩方案。结果表明，防眩策略能有效减少铁路前照灯对公路侧司机的眩光影响。



Abstract:According to the contrast principle of ambient light intensity for disability glare， a process of disability glare analysis based on three-dimensional spatial relationship model is proposed. Taking same-layer arranged highway and railway on the lower deck of a cable-stayed truss bridge as the engineering background， a case study is carried out. When no glare-resistance measures are taken for parallelly arranged highway and railway in close range， the glare effect produced by headlamps of railway train is serious， which is far beyond the threshold requirements of the relevant codes. Finally， an assemblable and three-dimensional glare-resistance strategy is proposed， and a detailed glare-resistance scheme is given in the case study. The results show that the glare-resistance strategy proposed can effectively reduce the glare effect of railway train headlamps to the drivers on highway.
