毗邻隧道连接段进口处视觉变化及合理照度研究

Visual Change and Reasonable Illuminance Study of Entrance of the Connecting Section of the Adjacent Tunnel

毗邻隧道由于其相邻隧道的间距较小,驾驶员在通过毗邻隧道时会在较短时间内经历“暗—明—暗”的视觉变化过程,对行车安全将会产生影响。利用SMI生产的ETGTM眼镜式眼动仪、照度计等仪器,对毗邻隧道进口处以及连接段进口处进行了大量的行车试验,通过数据分析得出了毗邻隧道进口处的瞳孔直径和连接段进口处的瞳孔直径之间的差异以及其与连接段长度之间的二次函数关系,提出了毗邻隧道是否按照普通隧道进行照明设计的临界长度。同时,通过分析毗邻隧道进口处瞳孔直径与照度之间的关系,得到了两者之间的函数关系式,并将该函数关系式运用于连接段进口处,提出了连接段进口处相应瞳孔直径下的合理照度值。所得结果对毗邻隧道连接段进口处的照明设计具有一定的参考价值。

Adjacent tunnels have a small distance between tunnels,and the driver will experience the“dark-light-dark”visual change process in a short time when passing through the adjacent tunnel,which will affect the driving safety.This article uses ETGTM Eyewear Eye Tracker produced by SMI,lumeter and other instruments to carry out a large number of driving tests on the entrance of the adjacent tunnel and the entrance of the connecting section.Through the data analysis,the quadratic function relationship between the diameter of the pupil adjacent to the entrance of the tunnel and the diameter of the pupil at the entrance of the connecting section and the length of the connecting section are obtained,and the critical length of whether adjacent tunnels are designed according to ordinary tunnels is proposed.At the same time,by analyzing the relationship between the diameter of the pupil at the entrance of the adjacent tunnel and the illuminance,the functional relationship between the two is obtained.and the function relationship is applied to the entrance of the connecting section,and the reasonable illuminance value under the corresponding pupil diameter at the entrance of the connecting section is proposed.The results obtained in this paper have certain reference value for the lighting design at the entrance of the adjacent tunnel connection section.
