摘　　要：通过分析隧道驾驶者的注视点,提出了不同车型驾驶者的等效光幕计算方法;建立了隧道仿真模型,利用仿真结果,计算了眩光阈值增量,探究了不同车型下灯具布设间距、高度对眩光等级的关系。研究结果表明:增加灯具布设高度可有效减小眩光影响,不同车型眩光差异变小;增加布灯间距会使眩光轻微加剧,不同车型眩光差异几乎不变。因此,隧道照明时可增加布灯高度、在一定范围内增加布灯间距,达到安全照明的效果。研究结果对于公路隧道照明灯具设置具有参考意义。The glare of luminaires will bring danger to drivers of highway tunnels.In this paper,by analyzing the attention of the tunnel driver,the equivalent light curtain calculation method for drivers of different vehicle models is proposed.A tunnel simulation model is established.Using the simulation results,the glare threshold increment is calculated,and the lighting arrangement distance under different vehicle models and the relationship between height and glare level ave explored.The results of the study indicate that increasing the height of the lamp arrangement can effectively reduce the glare effect,and the difference in glare between different models becomes smaller;increasing the distance between the lamps will slightly increase the glare,and the difference in glare between the different models is almost unchanged.Therefore,when lighting tunnels,the height of the lights can be increased and the distance between the lights can be increased within a certain range to achieve the effect of safe lighting.The research results have reference significance for the setting of highway tunnel lighting fixtures.
