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.
