摘要
为合理布置隧道施工LED灯具,充分发挥其照明优势,依托京沪高速济南连接线港沟隧道,采用DIALux照明模拟软件得到隧道已二衬段照明效果与各影响因素之间的关系,并通过现场实测确定了最佳照明方案。结果表明,布灯角度、高度总体上对照明效果影响较小,增大功率可近似线性提高平均照度而对均匀度影响甚微,当布灯间距过大时灯具照明叠加效果减弱,平均照度与均匀度将显著下降。
In order to arrange LED lighting in tunnel construction rationally and give full play to its lighting advantages,the relationship between lighting effect and influencing factors in the secondary lining section is obtained by using the lighting simulation software DIALux,based on the Ganggou tunnel in the Ji'nan connecting road of Beijing-Shanghai Expressway. The best lighting scheme is also determined through the in-situ measurement. The results show that the angle and height generally have little effect on the lighting effect,but increasing the power can almost linearly increase the average illuminance and has little effect on the uniformity. When the distance between two lamps is too long,the lighting superposition effect will be weakened and the average illuminance and uniformity will both decrease significantly.
