渝万高铁光裕寨隧道顺利贯通
Zhong Guo Xin Wen Wang· 2025-12-05 06:30
渝万高铁光裕寨隧道顺利贯通 中新网重庆12月5日电 (张旭)记者从中铁十一局获悉,12月5日,由该局承建的渝万高铁全线第二长隧道 ——光裕寨隧道顺利贯通,项目建设取得关键进展。 图为渝万高铁光裕寨隧道进口。张旭 摄 光裕寨隧道位于重庆市万州区,全长8575米,最大埋深约350米,系渝万高铁全线重难点控制性工程之 一。隧道穿越区段地质条件极为复杂,广泛分布缓倾岩层、软弱围岩等不良地质体,施工难度极大。 同时,该隧道还面临下穿既有交通干线的严峻挑战。其中,进口端下穿达万铁路,出口端下穿G42沪蓉 高速,立交处隧道结构距路基面最小净距仅19米,施工管控要求极高。 面对复杂地质环境,中铁十一局项目团队采用"中部斜井+出口横洞"辅助坑道方案,实现长隧短打、高 效推进目标。 施工过程中,项目团队创新应用多项先进工艺攻克地质难题:进口下穿段采用控制爆破与非爆结合的两 台阶开挖法,出口下穿段实施非爆三台阶开挖,同步优化光面爆破工艺。此外,工作人员还通过全程跟 班作业、动态调整参数,显著降低围岩扰动,有力保障既有线路安全。 图为隧道贯通点。中铁十一局供图 中新经纬版权所有,未经书面授权,任何单位及个人不得转载、摘编或以其它方式 ...
