摘要
根据小波理论.利用小波多分辨分析方法.分解反射波桩基检测波形.给出不同分辨率、不同时刻的波形分解结果。这样.可以对检测波形的各种成分及局部特征进行分析研究、从而.减少了干扰.突出了桩基缺陷的反射波特征.大大提高了桩基质量检测的分辨率和准确率。
Based on the wavelet theory. the wavelet multiresotution analysis method can be used to disintegrate the wave form of the rellected wave pile of foundation detection, to give the wave form disintegration result for different resolution at different times. In this way, it can conduct analysis and study for the different constituents and local characteristics of the detected wave forms. Thence, the interferences can be reduced, the reflected wave characteristics of the pile foundation defects are stressed. Thus. it greatly enhances the resolution and precision for the pile foundation quality detection.
