摘要
以湖北省某山区高速公路的隧道工程为依托,选择了其中几个具有代表性的隧道进行了调研,得到了不同隧道进出口处的照度、车速、车速差等数据,构建了隧道入口处的照明过渡技术指标,通过回归分析得出了车速差与照明过渡指标的关系,评价了隧道出入口亮度过渡对隧道安全的影响。
Based on tunnel project in a mountain areas highway of Hubei province, summarized and analyzed the typical and representative tun- nel project, plenty of data including illuminance, velocity subtraction and so on is obtained. The technical indicators of transition iUuminance at the entrance of tunnel was constructed, the relationship between velocity subtraction and transition illuminance was obtained by regression analy- sis. At last, the influence of luminance transition in tunnels passageway on tunnel safety was evaluated.
