Abstract
- Aiming at the defect happened in existing bridges, a side-excitation way is adopted. Here, the mutual interfere phenomenon between P-wave and S-wave will appear, which certainly will be influence the reflection of the information from fault position. In the paper, considering that the multi-resolution and local features within time-frequency of signal can be appeared by wavelet transform, a defect diagnosing method which utilize eigencurves of acceleration responses is presented, a group typical eigencurves which fit for reinforced concrete piles are given.
