| 摘 要： | 为了获得更加合理的隧道入口段亮度设计值,首先分析了隧道入口段亮度的确定方法,指出了Adrian和Augdal提出的等效光幕亮度计算方法中,都因为忽略了某些计算项而造成得到的极坐标圆环边界视角存在一定的误差;为解决该问题,提出采用数值积分的方法确定各圆环边界的对应视角,并给出了计算得到的各圆环边界视角值和由此得到的等效光...

| Abstract: | In order to design more rational threshold zone luminance of road tunnel,the determination methods of tunnel threshold zone luminance were analyzed,and the defects of equivalent veiling luminance calculation methods suggested by Adrian and Augdal,that is both methods will generate some errors of ring's border angles in polar coordinate graph because of the neglect of some terms in calculation process,were pointed out.In order to reduce the error,the ring's border angles in polar coordinate graph were calcul... |
