摘要
介绍了小波变换的原理,在此基础上讨论了小波分解及滤波在基桩完整性检测信号中的应用.结合工程实例,选用具有线性相位的双正交样条小波biorthogonal系列小波基bior5.5小波基对桩基检测信号进行了分解和滤波处理,并将其与常规分析方法进行了比较,初步探讨了各自存在的优缺点.
Based on the theory of wavelet transform, the application of wavelet decomposition and wavelet filter for the signals of pile integrity testing is introduced. Combining with engineering examples, bior5.5 is chosen which is a wavelet base of biorthogonal series that are biorthogonal spline wavelet with linear phase. By comparing with the normal analysis methods, both advantages and defects of them are discussed.
