摘　　要：水库工程帷幕灌浆先导孔钻探地质状况分析是水库工程防渗处理工艺要求较高的隐蔽工程帷幕灌浆重要技术环节,对水库工程帷幕灌浆质量具有十分重要的工程意义。为此,结合板丛水库工程帷幕灌浆先导孔钻探地质状况分析典型案例展开分析研究。熟悉工程概况,了解板丛水库坝址区地质现状;并着重从先导孔目的和任务、先导孔钻探地质状况(包括W-I-1号、W-I-9号、W-I-193号、W-I-201号钻孔地质情况及先导孔钻探地质现状判断结果等)两方面进行先导孔钻探地质状况分析。The geological condition analysis of pilot hole drlling for curtain grouting of reservoir engineering is an important technical link of curtain grouting of concealed engineering with high seepage control process requirements in reservoir engineering,which is of great engineering significance to the quality of curtain grouting process of reservoir engineering.Therefore,the typical cases of geological condition analysis of pilot hole drillingfor curtain grouting in Bancong Reservoir project are analyzed and studied.The results show that to familiarize with the project overview,one needs to understand the geological status of the Bancong Reservoir dam site area;And focus on analyzing the geological conditions of pilot hole drilling from two aspects:the purpose and task of the pilot hole,the geological conditions of the pilot hole drilling(including the geological conditions of drilling W-I-1,W-I-9,W-I-193,W-I-201,and the judgment results of the geological conditions of the pilot hole drilling).
