本文详细地介绍了石头河水利枢纽的基本地质条件,采用高密度电法探测出了断层及破碎带的位置,探讨了坝基稳定、坝基及绕坝渗漏和坝基开挖边坡稳定等工程地质关键问题,并通过分析评价给出了处理措施.利用现场勘查地质分析结果,比选出最合适的坝址,为类似建坝工程提供参考.

The basic geological conditions of Shitou river water conservancy project were introduced in detail.The location of faults and fracture zones was detected by high-density electrical method.The engineering geology key problems of dam foundation stability,dam foundation and dam leakage and dam foundation excavation slope stability were discussed,and the treatment measures were proposed by analysis and evaluation.With aid of the site survey geological analysis results,the most suitable dam site was selected,which can provide reference for similar dam construction projects.
