瞬态瑞雷波法在堤防防渗墙质量检测中的应用研究

针对目前堤防防渗墙质量检测内容和检测方法的不足，利用瞬态瑞雷波法对堤防防渗墙质量检测进行了分析研究，得出了套井回填粘土防渗墙各测点瑞雷波频散曲线及反演分析结果，给出了套井回填粘土防渗墙墙体内部缺陷及施工深度。通过与现场钻孔取样室内土工试验资料进行对比分析，得出了瑞雷波波速与介质干密度的相关关系，为堤防防渗墙工程的质量的控制提供了一种快速有效的检测方法。

Research on application of instantaneous Rayleigh wave method to inspection of dike cutoff wall quality

Aimed at remedying the defect in quality inspection of dike cutoff wall, the dike cutoff quality inspection is studied and analysed by using instantaneous Rayleigh wave method. The results of Rayleigh wave curve of frequency distribution and inversion analysis is achieved about all or measuring points of jacket-well refill clay cutoff wall. The inner defects and construction depth of jacket-well refill clay cutoff wall is given. Through contrasting and analyzing indoor soil meachanics test data in situ drill hole sampling, the correlation relationship between Rayleigh wave velocity and medium dry density is achieved. The quick and efficient method is presented for controlling the quality of dike cutoff wall engineerings.
