摘要
小湾水电站建设过程中采用了超声波、钻孔变形模量和全孔壁数字成像等物探检测技术手段,对坝基岩体进行物性参数的测试.通过多种测试成果的综合分析与研究,揭示了坝基岩体波速分布特征、波速衰减特征、裂隙发育规律等,为解决复杂的工程地质问题提供了基础依据,在小湾水电站的设计、施工、科研工作中起到了重要作用.
In Xiaowan hydropower project,we used acoustic waves,borehole elastic modulus and borehole imaging geophysical testing method on the dam foundation rock mass testing.By the comprehensive analysis and research of the various test results,we revealed the velocity distribution characteristics,attenuation characteristics and velocity fracture law of the foundation rock.These results provided the basis to solve the complex engineering geological problems and play important roles in design,construction and scientific research in Xiaowan Hydropower Project.
