摘　　要：水利工程大坝基础岩性质量检测结果深刻影响着大坝的质量与安全。为探究翁源县上庙水库大坝基础裂缝发育情况与岩体完整性,详细介绍了单孔声波测试法的计算原理、操作流程、适用范围,分析了运用该方法对工程岩体完整性检测中可能出现的难点以及对应解决措施,并对6个钻孔进行检测分析。结果表明:6个钻孔中ZK-108的岩体破碎,ZK-360与ZK-366的岩体较破碎,ZK-399的岩体完整性较差。说明该水库大坝的基岩承载力较弱,需要采取局部帷幕灌浆的方式进行加固处理,为其他工程的岩体检测提供了方法与经验参考。The quality inspection results of rock foundation in hydraulic engineering dams have a profound impact on the quality and safety of dams.To explore the development of foundation cracks and rock integrity of Shangmiao Reservoir Dam in Wengyuan County,this paper provides a detailed introduction to the calculation principle,operation process,and applicable scope of the single hole acoustic testing method.It analyzed the possible difficulties and corresponding solutions in using this method to detect the integrity of engineering rock masses,and conducted detection analysis on 6 boreholes.The results show that the rock mass of ZK-108 in 6 boreholes is fragmented,the rock masses of ZK-360 and ZK-366 are relatively fragmented,and the rock mass integrity of ZK-399 is poor.It indicates that the bearing capacity of the bedrock of the reservoir dam is weak,and local curtain grouting is needed for reinforcement treatment,providing a method and empirical reference for rock mass testing in other projects.
