| 摘 要： | 文中多次测量隧道进口瞳孔照度,利用视觉负荷指标,获得理想照度曲线,并用于对6种不同形式的正削竹、反削竹遮光设施的遮光效果进行分析和比选.结果显示,隧道微缩模型能较好模拟真实隧道进口瞳孔照度过渡;遮光设施遮光效果由优及劣的顺序依次为：30°反削竹、45°反削竹、30°正削竹、45°正削竹、60°反削竹、60°正削竹、端墙式.结论：30°反削竹遮光设施遮光效果最佳;相同角度遮光设施形式,反削竹遮光设施比正削竹遮光效果好.

| Abstract: | In this paper,multiple measuring on tunnel entrance pupil illumination and using visual load index,the ideal illumination curve and the analysis and comparison on shading effects of 6kinds of different forms of bamboo-truncating shading facilities are obtained.Results show that tunnel miniature model can better simulate the real tunnel entrance pupil illumination transition.The sequence order of the shading effect of shading facilities from optimal to worst is 30 down degrees bamboo-truncating,45 down degrees bamboo-truncating,30 up degrees bamboo-truncating,45 up degrees bamboo-truncating,60 down degrees bamboo-truncating,60 up degrees bamboo-truncating,retaining wall.Conclusion：shading effect of 30 down degrees down bamboo-truncating facility is best;With the same angle shading facilities forms,shading effect of the down bamboo-truncating shading facility is better than the up bamboo-truncating. |
