Non-Destructive Pile Integrity Test Using HWAW Method
The evaluation of soundness of pile is very important for safety of super structure. In this paper, the HWAW(Harmonic Wavelet Analysis of Wave) method is modified and applied to evaluate soundness of pile non-destructively. The proposed method can evaluate pile integrity such as pile length, material quality represented by wave velocity and pile end condition which are very important factors for pile behavior. To verify the applicability of proposed method, the numerical simulation test using ABAQUS was performed. A model pile was made and the proposed method was applied to evaluate soundness of model pile. Through numerical simulation and model tests, it is shown that the HWAW method has good potential of applying in the evaluation of pile integrity.
