申家坡隧道不良地质超前预报与治理研究

隧道施工过程中掌子面前方的工程地质和水文地质情况的复杂多变往往给隧道施工带来种种不确定因素和安全隐惠，隧道不良地质现象超前预报是确保施工安全的关键措施。申家坡隧道运用地质雷达对隧道掌子面前方的不良地质现象进行预报，同时结合新奥法现场监控量测，起到了反馈支护设计、评价治理方案、保障工程质量、规避风险事故的效果，具有重要的工程应用价值。

Study on Forecasts and Treatment of the Shenjia Slope Tunnel Adverse Geological

Complex and changeable engineering geology and hydrogeology characters of the front working face can lead to all sorts of uncertain factors and potential safety problems during the tunnel construction, the tunnel forecasts in advance of adverse geological phenomena are key measures to ensure the construction safety. Through the project of shenjia slope tunnel, applying Ground Penetrating Radar to predict adverse geological phenomenon of the front working face in the tunnel with combination of New Austrian Tunnelling Method to guide the construction and feedback the supporting design, it has an important engineering value to ensure the quality of the project, evaluate treatment effects and avoid the risk of accidents.
