摘要

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。

Abstract

Deconvolution is a main method for improving the seismic recording resolution. Its basic idea can be applied to the signal processing of the testing on the high-piled beam piled. The wharf piles were simulated by LS-DYNA explicit analysis method and the Low-strain Reflected Wave Method was used in the detection. Then, the testing signal was analysised by the Deconvolution Method. The numerical results illustrate that the Deconvolution Method can effectively restore the practical status of the pile and solve the problem that the defects signal can’t be identified when hammered on the panel. It provides a new way in the signal processing of the testing on the high-piled beam piled.
