摘　　要：为满足行车安全和运营维护要求,北京地铁13号线清河站两端地上区间照明灯杆高度由原6.1 m调整为4.0 m,地上区间灯具布置方式与既有线保持一致。由于缺少区间碎石道床类路面的亮度系数,采用点光源照度计算方法,对在不考虑反射光通量产生照度的地上区间照明方案进行讨论和研究。利用DIAlux照明计算软件进行模拟计算,提出采用常规照明方式,截光型灯具交错布置,灯具光源距轨平面≮2.5 m能够满足地上区间平均照度要求,为进一步提高路面亮度总均匀度和纵向均匀度,还需增加灯具高度角70°以外的光强值。To meet traffic safety and operation and maintenance requirements, the lighting poles in the aboveground section of Qinghe Station on Line 13 of Beijing Metro are adjusted from the original height of 6.1 m to 4.0 m. However, the arrangement of the lamps in the aboveground section is consistent with the existing aboveground section. Due to the inefficient brightness coefficient of the aboveground section gravel bed pavement, the illumination calculation method of point light source is adopted to explore the lighting scheme of specific places without considering the illuminance caused by the reflected light flux. DIAlux lighting calculation software is used to conduct simulation calculation. It is proposed that according to the conventional lighting method, the cut-off luminaire is adopted with staggered arrangement, and the illuminance source less than 2.5 m from the rail top can meet the average illuminance requirement of the aboveground section. To improve overall uniformity of road surface luminance and longitudinal uniformity of road surface luminance, it is necessary to increase the light intensity value beyond 70°of the height angle of the lamp.
