摘　　要：深山峡谷区建设的高等级公路,往往在穿越山脉时设置特长乃至超特长隧道。以昭通至西昌高速公路四川段项目的金阳隧道区段总体设计为例,简述高速公路越岭段总体设计,分析超长越岭隧道轴线方案如何选择,提出分析比较思路和总体设计原则。High-class highways built in deep mountain and canyon areas often set up extra-long or even super-long tunnels when crossing mountains. In this paper based on the overall design of the Jinyang Tunnel on the Sichuan section of the Zhaotong-Xichang Expressway project, the overall design of the expressway across mountain section is briefly described. How to choose the axis scheme of the super-long cross-ridge tunnel is analyzed, and the analysis, comparison ideas and overall design principles are put forward.
