综合超前地质预报技术在预报断层破碎带中的应用

Integrated advanced geological forecasting technology in forecast application in fault fracture zone

介绍了目前隧道超前预报的主要手段,着重对地质调查法和物探法的优缺点进行了探讨,并经工程实践证明,将两种预报手段相结合,利用数据统计及物性变化分析,可做到对隧道前方地质情况的定性与定量预测。这种预报方法在栋梁坡隧道断层破碎带预报中得以运用,取得了较好效果。

Introduced the main means of present tunnel advanced prediction,emphatically discussed the advantages and disadvantages of geological survey method and geophysical exploration method,and proved through the engineering practice. Combining the two forecasting methods and using data statistics and physical property change analysis can make qualitative and quantitative predictions of the geological conditions ahead of the tunnel. This forecast method was used in the fault fracture zone prediction of Dongliangpo tunnel and achieved good results.
