中新网曲靖11月25日电 (吴栋良)25日，由中铁十八局承建的大坪隧道贯通。至此，渝昆高铁云南段隧道已贯通48座，隧道贯通已超90%。
大坪隧道位于云南省曲靖市会泽县境内，全长12.3公里，是全线控制性工程，为Ⅰ级高风险隧道。隧道地处云贵高原喀斯特地貌区，地形起伏大、岩溶发育，隧道穿越2处断层、1处向斜，Ⅳ、Ⅴ级围岩占比近70%，围岩破碎、稳定性极差，开挖时极易出现塌方等险情，而且地下水丰富，最大涌水量每天达3.7万立方米。
中铁十八局渝昆高铁项目部现场技术负责人宁赋岩介绍，施工中利用瞬变电磁、长距离超前钻孔等多种先进技术手段，2次精准预测出岩溶突水突泥风险，顺利通过了1800多米的极高风险段落，平导连续3个月掘进进度超过200米，为全隧按时贯通奠定了坚实基础。
从重庆到昆明，渝昆高铁正在加速建设，随着大坪隧道的贯通，渝昆高铁云南段隧道已贯通48座，隧道贯通已超90%。目前，渝昆高铁云南段全面进入冲刺阶段，每天投入1.4万余名施工人员，1500余台大型机械设备，全力推进重难点项目建设，路基土石方工程已完成99.5%，桥隧施工完成98.6%。
渝昆高铁全长约700公里，其中云南段长388.6公里，设计时速350公里，是云南省内首条时速达350公里的高速铁路。全线建成通车后，重庆到昆明的行车时间将大幅压缩，对构建新发展格局、促进沿线地区经济社会高质量发展具有重要意义。(完)
