摘　　要：文章对某电站处于高地应力区的坝基物探检测工作做了全面的技术总结,通过对单孔声波、跨孔声波、表面地震波及钻孔全景成像检测等物探成果资料的分析,得出了坝基岩体波速衰减率、波速、松弛深度等力学参数和裂隙宽度、走向等地质特征,为岩体质量做出了客观的评价,为大坝基础质量验收及安全评价提供有力的技术支持。The physical exploration inspection for the dam foundation of a hydropower station in the high crustal stress is fully described technically. Through analysis of the exploration results such as sonic wave in single drill hole, sonic wave across drill holes, surface earthquake wave and full image inspection in drill hole, the mechanic parameters of attenuation rate, wave velocity, slack depth, etc of the wave velocity of the dam foundation rock mass and the geological characteristics of fracture width and strike, etc are obtained as well as the rock mass quality is assessed objectively. These provide quality acceptance and safety assessment of the dam foundation with strong technical support.
