Experimental Study on Detection Method to Butt Strap Based on Wavelet Transform |
| |
| Abstract: | Aimed at the problem that it is hard to detect void of expressway bridge butt strap,ground penetrating radar is used to conduct detection through physical model test of butt strap.Signals are disposed and analyzed by wavelet transform method to reduce noise and enhance signal to noise ratio,which provide references for this defect treatment. |
