摘  要:采用白色涂料、长余辉发光涂料和水泥抹灰砂浆为隧道侧壁涂装材料对兴义环城高速的3条隧道的中间基本段进行了涂装,测定了3种涂装方式下隧道中间基本段的地面亮度和墙面亮度,探讨了侧壁涂装方式对隧道光环境的影响。结果表明,白色涂料和长余辉发光涂料能提升隧道内部墙面亮度和地面亮度,降低隧道内部空间的炫光值,并提升墙面与地面的对比度;水泥抹灰砂浆涂装的墙面隧道空间亮度值和地面亮度值均最低,墙面与地面的亮度对比值较低。

Abstract: The middle basic sections of three tunnels of Xingyi ring expressway were coated with white paint, long afterglow luminescent paint and cement mortar. The ground brightness and wall brightness of the middle basic section of the tunnel under three coating methods were measured, and the influence of side wall coating methods on the light environment of the tunnel was discussed. The results show that white paint and long afterglow luminescent paint can improve the brightness of the wall and ground inside the tunnel, reduce the glare value of the space inside the tunnel, and improve the contrast between the wall and the ground; the wall surface coated with cement plastering mortar has the lowest brightness value of tunnel space and ground, and the brightness contrast value between wall surface and ground is low.

Key Words: Tunnel; Middle section; Sidewall coating; Brightness; Contrast ratio

公路隧道具有缩短里程、节约时间、节约用地、提高交通运输效率、生态环保等优点,在山区高速公路建设中应用广泛。然而,隧道洞内通常表现为低照度、小空间和单调的封闭环境,且受到“黑洞白洞”效應问题的困扰[1-3]。通过增加电光照明灯具可有效缓解“黑洞白洞”效应问题,但过多照明灯具的设置造成了隧道运营的高能耗与高成本,同时也衍生出了“眩光”问题。隧道侧壁作为视野感知域的重要组成部分,对驾乘人员清楚辨识洞内障碍物具有重要影响,提高墙面和地面的对比度有利于提高公路隧道的安全系数[4-8]。

借助现代先进技术手段,提升驾驶员的生理、心理应急能力,打造节能型和安全型隧道光环境是当今公路交通运输行业科研工作亟需解决的问题。……
