Wavelet Function Choosing in Wavelet Transform of Pile Integrity Dynamic Test Signals

摘要：

In some cases, wavelet transform method is needed to analysis the test signal and the key problem of the wavelet transform method is wavelet function chose. So in this paper some wavelets utilized in engineering usually as Harr wavelet, Daubechies wavelets, Mexican Hat wavelet was applied in wavelet transform of pile signal which brought by breaking pile. Through model pile testing signal contrast analysis such result as Harr wavelet and Daubechies wavelets are adapt to pile testing signal wavelet analysis. And then through contrast analysis the Db5 wavelet was decided as a best one for pile testing signals analysis.
