金鱼隧道涌水处治技术

绵茂公路一期工程金鱼隧道隧址区含水丰富，部分地段涌水，针对此情况，通过对隧址区水文地质进行调绘及对涌水原因的分析和涌水量的计算，制定了不同的处置方案，并进行比选，采用了安全性最好的拦排相结合的施工技术，最终成功解决了该隧道的涌水问题

Treatment Technology for Water Gushing in Jinyu Tunnel

The area of Jinyu tunnel is rich in water in the first-stage project of Mianmao highway and part of sections have water gushing. As for this conditions, through the the cause analysis, the calculations of water inflow and the hydrogeological survey, different treatment measures are developed. Through the comparison and selection,techniques that combining grouting and blocking water with drainage are adopted which are proved to be the most safe technique and succeed in solving the problem of water gushing ultimately.
