摘　　要：掌握隧道减光格栅段路面照度分布特征和时变特性是进行减光格栅设计和光环境评价的基础。本文基于太阳辐射理论和CIE亮度分布函数构建了同步考虑太阳直射和天空散射的隧道减光格栅段路面全天候照度计算模型,并通过实测数据验证模型的准确性和有效性。结果表明,该模型可准确预测不同季节和天气条件下减光格栅段路面亮区和暗区照度的时空变化规律,计算结果与实测数据吻合良好(平均偏差百分比<8%)。增加天空元数量可提升本文模型的计算精度,且对路面暗区照度计算值的影响更大。综合考虑精度与计算效率,建议应用本模型时天空划分为12层共247个天空元。Understanding the characteristics of road illuminance distribution and temporal variation in the tunnel light reduction grille section is essential for the design of light reduction grilles and the evaluation of the lighting environment.The paper constructs an all-weather road illuminance calculation model for the tunnel light reduction grille section that takes into account both direct sunlight and sky scattering based on solar radiation theory and the CIE luminance distribution function.The accuracy and effectiveness of the model are validated through measured data.The results indicate that the model can accurately predict the spatiotemporal variations of illuminance on the bright and dark areas of the road surface in the light reduction grille section under different seasons and weather conditions.The calculated results aligh well with the measured data,with an average deviation percentage of less than 8%.Increasing the number of sky elements can enhance the calculation accuracy of the model proposed in this paper,with a greater impact on the illuminance calculation values in the dark areas of the road surface.Considering both accuracy and computational efficiency,it is recommended to divide the sky into 12 layers with a total of 247 sky elements when applying this model.
