中国现有公路隧道2889个,其中特长隧道有43个、165．9公里。今后一段时期,中国公路建设将持续增速,且主要集中在中西部地区,公路隧道数量也将进一步快速增长,保证隧道交通流的安全畅通逐成为隧道运营管理单位的关注热点。除了运用先进的车流组织理论和采用稳定的机电设备,研究司机的行为特征、驾驶习惯以及使隧道的设计、施工、使用更加人性化,更应受到重视。本文介绍了燧石(即耐火石)反光、散热、价格低廉等特性,以及在隧道施工中,其作为增亮剂与沥青混合后加铺,改善隧道内光线强度所达到的效果,并引用了在德国Keppelberg隧道改造工程中的应用实例。
There are 2,889 road tunnels in China, of which 43 are special tunnels and 165.9 km in length. In the coming period, China’s road construction will continue to grow rapidly, and will mainly be concentrated in the central and western regions. As a result, the number of highway tunnels will further grow rapidly. As a result, tunnel traffic management will become a hot spot for tunnel operation and management units. In addition to using advanced flow organization theory and using stable mechanical and electrical equipment, it is more important to study the driver’s behavior characteristics, driving habits and make the design, construction and use of the tunnel more humane. This paper introduces the characteristics of flint (ie, refractory stone) reflective, heat dissipation, low price and other effects, as well as the tunnel construction, as a brightening agent and asphalt mixture after the shop, to improve the light intensity within the tunnel achieved by the effect, Application Examples of Keppelberg Tunnel Rehabilitation Project in Germany.
