基于小波变换的搭板病害检测方法试验研究

Experimental Study on Detection Method to Butt Strap Based on Wavelet Transform

针对高速公路桥梁搭板出现脱空病害后难以检测的问题,通过搭板实体模型试验,利用地质雷达进行检测,采用小波变换方法对信号处理分析,降低噪声,提高信噪比,为该病害处理提供借鉴经验。

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.
