| Abstract: | The frequency variation mechanism of transmission impulse resulted from defects in steel-tube-concrete is presented by using dispersion theory. The foundation of applying wavelet theory to analyze the signal of the integrity detection for the steel-tube-concrete is developed. The characteristic values that can express the frequency variation of transmission wave are presented and validated by model tests. By decomposing multi-resolution wavelet to analyze the surface wave detection signal of steel-tube-concrete, the foundation of quantitatively evaluating the defect size is obtained. |
