为明确景观带在隧道领域的应用现状,对我国70座公路隧道进行调研和分析,分析景观带在公路隧道运营中的作用,对现有景观带的布设形式和应用效果进行系统梳理,最后提出相应的设计建议与展望。结果表明: 1)隧道景观带能够缓解驾驶员的心理压力和视觉疲劳,提升隧道的整体观感和行车舒适度,并增添文旅宣传;但由于目前缺乏成熟的设计规范,隧道景观带的设计偏主观。2)我国公路隧道景观带布设形式主要包括彩绘喷涂、LED动态网格屏、LED景观灯阵、投影及其他布设形式。3)隧道景观带在布设形式的选择上多采用投影与其他布设形式;除10 km以上的特长隧道外,大部分隧道景观带的布置数量为1个; 中、短隧道景观带长度多设为隧道全长。4)在景观带设计时,应当注重景观照明与基本照明的统一设计和景观设计的均衡性,并且遵循绿色、低碳的节能性原则。5)未来在景观带设计时,应构建刺激量与唤醒程度间的关系模型,将多方因素纳入考量,以期实现更为科学合理的景观带设计。
Herein, the effects of landscape belts in 70 highway tunnels are analyzed and their layout modes are systematically summarized. Additionally, comprehensive design suggestions and research prospects are provided. The results reveal the following. (1) Tunnel landscape belts alleviate drivers′ psychological stress and visual fatigue, enhance the overall aesthetics and driving comfort of the tunnel, and promote cultural tourism; however, because of the lack of mature design specifications, the design of tunnel landscape belts is subjective. (2) The layout elements of landscape belts in China′s highway tunnels primarily include painted areas, LED dynamic grid screens, LED landscape light arrays, and projection. Projection and other layout modes of landscape belts are popular choices in tunnels. (3) There is no more than one landscape belt in tunnels less than 10 km, and the length of the landscape belt is set as long as the short- and medi-long-tunnels. (4) Landscape belt lighting and tunnel basic lighting should be designed considering green and low-carbon principles. (5) In future studies, a relationship model between stimulation intensity and arousal level should be established, incorporating multiple factors, for the rational design of the landscape belts.
