新茨沟隧道软弱炭质片岩地段施工技术研究

Research on construction technique at weak carbon-based schist section along Xincigou Tunnel

针对新茨沟隧道软弱岩质片岩地段施工技术进行了研究,结合该隧道水文地质条件分析了施工难点,介绍了控制变形,侵限,水害,围岩扰动等情况的施工措施,并对施工效果作了具体阐述,为今后同类工程积累了宝贵经验。

The paper researches the construction technique at weak carbon-based schist section along Xincigou Tunnel,analyzes the construction difficulties by combining the hydrogeology condition of the tunnel,introduces the construction measures,including the control deformation,the clearance intrusion,the water disaster,and the disturbance of surrounding rock,and illustrates its construction effect,so as to accumulate precious experience for similar projects in future.
