摘　　要：通过当前借助隧道超前地质预报技术对隧洞中断层判定在业界已取得了一定的成果,但实际在引水隧道工程中往往也面临着地质条件复杂多变的断层,而能准确探测出这些断层对于保障引水隧洞的安全开挖是一项急需迫切解决的研究。此次研究采用TSP法进行,分析了在断层中对TSP的数据采集主要因素,并对滇中引水工程中两处隧道断层的地质情况进行探测,通过资料处理及对比分析,最终与开挖结果进行验证,取得了较好的预报效果,为引水隧洞断层段的预报分析提供了较好的参考。Through the current use of advanced geological prediction technology in tunnels,certain achievements have been made in the industry to determine the interruption layer of tunnels.However,in actual water diversion tunnel engineering,there are often complex and variable geological conditions of faults.Accurately detecting these faults is an urgent research that needs to be addressed to ensure the safe excavation of water diversion tunnels.This study used the TSP method to analyze the main factors for data collection of TSP in faults,and explored the geological conditions of two tunnel faults inCentral Yunnan Water Diversion Project.Through data processing and comparative analysis,it was finally verified with excavation results,achieving good prediction results and providing a good reference for the prediction and analysis of the fault section of the water diversion tunnel.
