| 摘 要： | 快速、有效地检测水库大坝质量对于保障水库大坝的安全是十分重要的。结合工程实际,应用瞬态瑞利波法、地震层析成像法对拱坝质量检测进行了研究分析。得出了拱坝坝体各测点瑞利波频散曲线、各层介质剪切波速度反演分析结果及两探测孔间坝体介质波速分布图,给出了拱坝坝体内部缺陷并查明了拱坝病害的主要原因,为水库大坝除险加固提供了可靠的依据。

| Abstract: | The application of the methods of both the instantaneous Rayeigh wave and the seismic tomography to the quality inspection on arch dam are studied and analysed based on the relevant engineering practice;from which the Rayleigh wave dispersion curve of all the measuring points on the body of the arch dam,the result of inversed analysis on the shear-wave velocities of all the layers of media and the distribution of the wave velocity of the media for the body between two inspection drilling holes are obtained and the internal defects in the dam body are given,and then the main causations of the diseases on arch dam are found out as well.On the whole,the research makes a reliable basis for the dam strengthening projects concerned. |
