在隧道行业相关单位的大力支持及既有统计数据的基础上，对截至2023年底中国已建成运营、正在建设、规划设计的共计74座长度10 km以上的特长公路隧道进行统计，其中,已建成运营特长公路隧道25座，正在建设特长公路隧道31座，规划设计特长公路隧道18座。从隧道长度、所在省份、公路等级、地理位置、技术标准、施工工法、设计与施工单位等方面，对中国已建成运营、正在建设、规划设计的长度10 km以上的特长公路隧道建设情况进行分析，其中： 长度在10~14.9 km的隧道共62座，长度在15~19.9 km的隧道共10座，长度大于20 km的隧道共2座；隧道主要集中在中国西南部，约占63%，四川省最多，其次是云南省；高速公路隧道达65座，占比约为88%；山岭公路隧道68座，水下隧道6座；隧道技术标准以双向4车道为主；隧道施工工法以钻爆法为主，近些年出现了TBM+钻爆组合工法；隧道设计单位主要有31家；隧道施工单位主要有52家。

With the strong support of relevant organizations in the tunnel industry and based on the existing statistical data, statistical analysis is made on 74 superlong highway tunnels over 10 km completed and in operation, under construction, and planned and designed as of 2023 in China. In which, there are 25 tunnels completed and inoperation, 31 tunnels under construction, and 18 planned and designed tunnels. Statistical analysis is conducted from the aspects of length, province, highway, location, technical standard, construction method, designer, and contractor. The analytical results show that there are a total of 62 such tunnels with a length of 10－14.9 km each, 10 with a length of 15－19.9 km each, and two with a length over 20 km each. These tunnels are mainly distributed in the southwest China, accounting for approximately 63%, and with the highest numbers in Sichuan and Yunnan provinces. There are 65 expressway tunnels, accounting for approximately 88%. There are 68 and six mountain and underwater tunnels, respectively. These tunnels are mainly subject to the twoway fourlane design and mainly constructed by drilling and blasting method. The combination method of TBM + drilling and blasting has emerged in these tunnels. There are 31 designers and 52 contractors, respectively.
