历经831个日夜奋战
雄忻高铁东冶隧道顺利贯通
这是雄忻高铁贯通的首座
长度超4000米的隧道
东冶隧道位于山西省五台县东冶镇，全长4320米，最大埋深177.36米。隧道埋深浅、围岩破碎、穿越6条断层破碎带，且隧道多处浅埋下穿采石场，在隧道开挖过程中软弱围岩变形大，极易出现地表沉陷、围岩失稳、掉块、塌方等状况。
施工单位通过引入3D隧道全断面自动扫描仪，进行精准计算与监测；配备全工况湿喷机械手等智能化施工装备，显著降低人工操作风险，为复杂地质条件下的工程建设筑牢安全屏障。
雄忻高铁是我国“八纵八横”高速铁路网京昆通道的重要组成部分，也是山西省首条设计时速350公里的高速铁路。
项目建成后，对山西更好融入京津冀协同发展战略、强化中部地区的大通道格局，促进区域经济社会高质量发展具有重要意义。
