【摘要】 在当前隧道超前地质预报变得日趋重要的情况下,本文详细探讨了如何选择合理有效的预报方法。首先分析了我国现阶段所有的超前地质预报方法的优缺点,然后通过对比分析,提出了隧道的超前地质预报以TSP法长距离探测为主,同时有效地与探地雷达短距离探测相结合的预报方案。通过对邵阳-怀化高速公路多个隧道的应用研究,此方案取得了很好的预报效果,给施工单位提供了有效科学的指导。更多还原

【Abstract】 The advanced forecast of geology in tunnel is becoming more and more important at present.It is deeply discussed how to chose a reasonable and effective way to the forecast.The advantages and disadvantages of the different methods for the advanced forecast of geology in our country are introduced.It is put forward that the TSP system should be taken as the main forecast method under some complicated geology conditions,and the GPR could be used as an assistant means for the advanced forecast.Through the application study in several tunnels of the highway from Shaoyang to Huaihua,the said method has obtained the satisfied results for the forecast,which provides the technical guide for the construction.更多还原
