山岭隧道排水技术研究

Study on Drainage Technology of Mountain Tunnel

现在世界各地越来越多的复杂开挖形式的公路隧道在山区修建,地下水涌入作为一种潜在的灾害,也是决定隧道开挖推进速度的重要影响因素。本文结合鸡鸣隧道工程施工实例对隧道涌水的主要形式和危害进行了简要分析,提出了一系列隧道开挖排水的主要技术措施,给相关山岭隧道排水建设工程提供参考。

Nowadays, more and more complicated road tunnels are built in mountainous areas all over the world. As a potential disaster, groundwater influx is also an important factor to determine the speed of tunnel excavation. Based on the construction example of Jiming tunnel, this paper briefly analyzes the main forms and hazards of water gushing in the tunnel,and puts forward a series of technical measures for drainage during tunnel excavation, which can provide reference for related mountain tunnel drainage construction projects.
