帷幕注浆法预加固隧道周壁围岩及止水理论与实践

对隧道穿越高压富水层时，应用超前地质预测预报，以普氏理论为依据，利用帷幕注浆法治理隧道水害的方法作了介绍，以湖北省翻三峡大坝高速公路鸡公岭隧道工程实例作佐证，对工程现场注意事项提出几点建议，为类似工程设计、施工提供借鉴。

The Theory and Practice of Reinforcing in Advance the Wall Rock of Tunnel and Waterproof Utilized by the Curtain Grouting

When the tunnel goes through the high hydraulic pressure layer, applying the preceding forecast and according to the Pushi Theory, the way of curtain grouting which is used for disposing the water disaster in the tunnel is introduced in the paper. It takes the Jigongling tunnel（the tunnel is in the highway which is crossed the Sanxia dam in Hubei Province） for proof, some advice in the engineering scene is given in this paper, some reference is offered in the same design certification and construction.
