反褶积是提高地震记录分辨率的主要方法，其基本思想可以应用于梁板式高桩码头桩基检测信号处理中。通过 LS -DYNA 有限元软件模拟高桩码头群桩结构，以低应变反射波法为检测手段，利用反褶积方法对测桩信号进行处理。数值结果表明，反褶积方法可以有效还原桩身实际状况，在一定程度上解决了面板激振等操作较为方便的检测方式下缺陷信号不易识别的问题，为高桩码头的方便、快捷检测提供了一种新的思路。

Deconvolution is a main method to improve a seismic recording’s resolution.Here,its basic idea was applied in signal processing of pile tests of a high-piled wharf.The wharf piles structure was simulated with LS-DYNA explicit analysis method and the low-strain reflected wave method was used for detection.Then,the testing signals were analyzed with the deconvolution method.The numerical results illustrated that the deconvolution method can effectively be used to restore the practical status of piles and solve a problem that defect signals can’t be identified when a panel is hammered.This study provided a new way in signal processing of pile tests of a high-piled wharf.
