公路隧道地质灾害探测技术探讨与实践

通过对邵怀高速公路多个隧道进行的应用研究，在对目前常用的工程地质调查、水平钻探、高频地质雷达和TSP探测等方法技术进行探讨的基础上，提出了长期预报与短期预报相结合、多种方法互为补充的公路隧道超前地质预报方法。

Discussion and Application of advanced exploration and forecast of geological disaster in Highway tunnel construction

Along with the implement of strategic of West-Open up of nation, the highway construct like a raging fire in westward. And in the face of mountainous area with complicated geological condition, tunnel is always adopted in design and construction. But during the construction of tunnel, many geological disasters such as collapse, peak-emit, water-emerging often occurred, which affected the plan and quality of tunnel construction seriously. So the advanced exploration and forecast of geological disaster already became a problem in need of research imperatively and arouse more and more attention and consideration broadly. On the base of discussion and ponder of the exploration technology such as engineering geology investigation, level drilling, geological radar and TSP203, the synthetical technology of advanced exploration and forecast of geological di saster--integrating long-range forecast with short-term forecast, and many measures supplement each otherwere brought forward after research and practice of many tunnels in Shaoyang-Huaihua highway. And then after application in many fact engineering, the effect is very favorable.
