摘要:

针对高速公路隧道群的定义问题,对普通隧道与隧道群的区别进行分析,全面考虑影响隧道群定义的因素,包括隧道通风、隧道照明、隧道消防安全、隧道交通安全、驾驶人视觉特性以及《公路隧道提质升级行动技术指南》(简称“技术指南”)中的规定,采用层次分析法,对以上因素进行重要性标度,计算得出各因素的权重,最终得出高速公路隧道群的定义间距。研究结果表明: 1)隧道通风和隧道消防安全对应的隧道群定义间距为400 m,当设计速度为80 km/h时,隧道照明、隧道交通安全、驾驶人视觉特性、技术指南各个因素对应的隧道群定义间距分别为300180480130 m 2)全面考虑各种因素后,得出设计速度为80100120 km/h时隧道群的定义间距分别为300350400 m

Abstract:

 The difference between ordinary tunnels and tunnel groups around the world is analyzed. The factors affecting the definition of tunnel groups are fully considered, including ventilation, lighting, fire safety, traffic safety, driver′s visual characteristics, and provisions in the Technical Guidelines for Quality Upgrade of Highway Tunnels. Then, the analytic hierarchy process is employed to gauge the importance of these factors. Moreover, the weight of each factor is calculated, and the defined distance of the when the design speed is 80 km/h, then lighting highway tunnel group is obtained. The results show the following: (1) The defined distances of tunnel groups corresponding to ventilation and firefighting are 400 m; when the design speed is 80 km/h, the defined distances of tunnel groups corresponding to lighting, traffic safety, driver′s visual characteristics, and technical guidance are 300、180、480, and 130 m, respectively. (2) By considering various factors, it is concluded that the defined distances of the tunnel group are 300, 350, and 400 m corresponding to design speeds of 80, 100, and 120 km/h, respectively.
