靖博 川观新闻记者 袁城霖 记者2026年1月1日从京昆高速铁路西昆有限公司获悉，当天上午，位于达州市宣汉县境内的万家山隧道顺利贯通。这是西渝高铁康渝段贯通的首座超6公里隧道，标志着西渝高铁建设取得新进展。 隧道贯通现场。 万家山隧道全长6465米，为单洞双线隧道，由中铁二院勘察设计、中铁六局承建。隧道地处大巴山区，施工过程中面临软岩大变形、有害气体等复杂多变的地质条件，安全风险高、建设难度大。 中铁六局西渝高铁康渝段站前四标项目部现场负责人说，建设团队按照“短进尺、弱爆破、强支护、勤量测”原则施工，引入拱架安装激光校准仪，大规模应用衬砌智能浇筑振捣系统、智能养护台车等工装，利用先进技术手段精准预测瓦斯风险及浅埋区段落，采用台阶法开挖，为隧道安全施工、按时贯通奠定坚实基础。 隧道进口。 随着万家山隧道顺利贯通，西渝高铁康渝段已贯通43座隧道，路基、桥梁、隧道等站前主体工程建设正有序推进。 西渝高铁建成后将与成渝、郑渝、渝昆等高铁线路互联，西安至重庆的出行时间将大幅缩减，将推动中西部地区铁路路网结构进一步完善，极大便利沿线人民群众出行，对推进乡村全面振兴、助力城乡融合和区域协调发展、推动西部大开发形成新格局，具有十分重要的意义。 万家山隧道斜井二衬。 （中铁六局西渝高铁康渝段站前四标项目部供图） 【未经授权，严禁转载！联系电话028-86968276】
