| 摘 要： | 在低应变检测采集的数据中,会受到各种噪声的干扰。利用小波变换的时频局部化能力,对实测信号进行降噪处理,可保留信号的突变特征,抑制噪声信号。在实际应用中证明小波分析对低应变检测信号的降噪是一种比较好的数据处理方法。

| Abstract: | When we collect pile testing data,it will be subject to various noises.In this paper,the wavelet transform time-frequency localization capability is used to measure signal noise reduction.The mutation characteristics of the signal are retained,and the noise is suppressed.It is demonstrated that the practical application of wavelet analysis in data denoising for low strain dynamic testing pile is a good data processing method. |
