WAVELET ANALYSIS METHOD OF SURFACE WAVE DETECTION FOR STEEL TUBE CONCRETE
钢管混凝土表面波检测的小波分析方法

The spectral variation mechanism of the transmitted pulse when surface wave meets a defect in steel tube concrete is explained by using the diffraction theory. The characteristic index for quantitatively evaluating the degree of defect damage is given through the method of wavelet analysis. Model tests are carried out,and the results of tests show that the method of surface wave detection and wavelet analysis for evaluating the integrity of steel tube concrete is effective,quick and more accurate.
