摘　　要：对截至2024年底中国铁路隧道、高速铁路隧道、特长铁路隧道情况进行统计。结果显示,截至2024年底,中国铁路营业里程达到16.2万km,其中,投入运营的铁路隧道18997座,总长24246 km;2024年新增开通运营线路铁路隧道424座,总长738 km;在建铁路隧道2521座,总长约6905 km;规划铁路隧道5634座,总长约13742 km。中国已投入运营的高速铁路总长超过4.8万km,共建成高速铁路隧道4917座,总长8279 km,其中,长度大于10 km的特长隧道120座,长约1536 km;2024年新增运营有隧道工程项目的高速铁路共12条,总长1981 km,共有隧道356座,长约544 km;在建高速铁路共58条,总长9866 km,共有隧道1412座,长约3509 km;规划高速铁路项目中含隧道2057座,长约4843 km。中国投入运营的特长铁路隧道共296座,长约4007 km,其中,长度20 km以上的特长铁路隧道14座,长约335 km;2024年新增运营特长铁路隧道10座,长约138 km;在建特长铁路隧道163座,长约2504 km;规划特长铁路隧道259座,长约3633 km。最后,对2024年新开通的重点项目佛莞城际铁路、成兰铁路、兰张三四线铁路和池黄铁路隧道的概况及特点进行介绍,并总结其技术经验。佛莞城际铁路通过地质选线,管片采用“双掺”技术、设置分布式凹凸榫等措施,有效降低了隧道施工安全风险;成兰铁路德胜隧道制定了大变形综合防治体系,并研发了双线合修隧道洞内救援站,提升了隧道变形防控和疏散救援能力;兰张三四线铁路借鉴既有施工经验,通过减灾选线和综合利用既有辅助坑道,显著降低了施工及运营期间的安全风险;池黄铁路隧道成功应用掌子面围岩质量分析技术,保障了隧道施工安全。中国在复杂环境下的大直径盾构隧道建造技术日趋成熟,应对复杂地质条件的隧道设计施工水平进一步提高,钻爆法隧道全工序机械化水平得到有效提升。The authors present statistical data on tunnels respectively on conventional railways,high-speed railways,and extra-long railways in China by the end of 2024.According to the data,China′s operating railways have reached a total length of 162000 km by the end of 2024.Among these operating railways,there were 18997 tunnels with a total length of 24246 km.New railways opened for traffic in 2024 incorporated 424 tunnels,with a total length of 738 km.There were 2521 tunnels located on railways under construction,with a total length of about 6905 km;there were 5634 tunnels located on railways under planning,with a total length of about 13742 km.The total length of high-speed railways that have been put into operation in China has exceeded 48000 km,incorporating 4917 tunnels with a total length of 8279 km.Among them,120 were extra-long tunnels with a length of more than 10 km each and a total length of about 1536 km.12 new high-speed railways with tunnels were opened in 2024,stretching for a total length of 1981 km and incorporating 356 tunnels,totaling about 544 km in length.There were 58 high-speed railways under construction with a total length of 9866 km,incorporating 1412 tunnels with a total length of about 3509 km.The planned high-speed railways included 2057 tunnels with a total length of about 4843 km.China had 296 extra-long railway tunnels in operation,with a total length of about 4007 km.Among them,14 were extra-long tunnels over 20 km each,with a total length of about 335 km.China′s new railways opened in 2024 included 10 extra-long tunnels with a total length of about 138 km.There were 163 extra-long tunnels located on railways under construction,with a total length of about 2504 km;there were 259 extra-long tunnels located on railways under planning,with a total length of about 3633 km.The authors also provide an overview of tunnels located on the new key projects opened in 2024,including Foshan-Dongguan intercity railway,Chengdu-LanzhoUrailway,Lanzhou-Zhangye No.3&No.4 line high-speed railway,and Chi
