| 摘 要： | 隧道穿越岩溶区域时,容易发生坍塌,涌水,突泥等事故,加大了施工的难度和风险,因此,在施工时辅之以地质预报是十分必要的。通过研究地质分析法、地质雷达、红外探测,超前水平钻孔等超前地质预报技术在某隧道中岩溶预报中的应用,提出针对岩溶地质条件的施工建议,并对照实际开挖情况,分析了由多种预报手段综合而成的预报系统的实用性以及在指导施工方面的重要作用。

| Abstract: | The collapse,gushing water and mud will be likely to occur as the tunnel crosses the karst area,which greatly increases the difficulty and risk of tunnel construction.Therefore,it is essential to predict geological conditions during the construction.Through analyzing the application of Geological Prediction Technologies(such as geological method,GPR(Ground Penetrating Radar),infrared water detector and horizontal pre-drilling) in the karst predication of a tunnel,the paper puts forward construction recommen... |
