| 摘 要： | 隧道渗水是隧道开挖过程中普遍面临的问题。老山隧道位于碳酸盐岩山区,该地区水文地质条件复杂、生态环境脆弱敏感,确定防治水的重点及对策是工程中面临的重要课题。本文结合老山隧道工程,在地质调查、隧道涌水观测与防治水现场试验的基础上,对老山地区的水文地质及地下水循环特征,特别是断裂控水规律作了深入研究,提出了碳酸盐岩地层富水性断裂的工程分类与防控对策;分析了结构防水的薄弱环节之成因,并提出了相应的工程对策。

| Abstract: | Laoshan tunnel runs through a carbonate region,and its hydrological and geological condition is complex and ecosystem is vulnerable.So it is important to analyze and determine the water-control measurements during tunneling process.Based on geological investigation,water seepage observation and site water-control tests,this paper presents the water-control focus of Laoshan tunnel and discussed the reason of the weakness of structure waterproof and the corresponding controlling methods. |

| Keywords: | Laoshan tunnel seepage classification water-control inject concrete seepage control |
