HWAW(Harmonic Wavelet Analysis of Wave) 방법을 사용한 말뚝기초의 비파괴 건전도 평가방법의 개발

Abstract

The evaluation of soundness of pile is very important for the safety of super structure. In this paper, the HWAW (Harmonic Wavelet Analysis of Wave) method which is developed to determine phase and group velocities of waves is applied to evaluate integrity of pile non-destructivly. The proposed method can evaluate a soundness of pile and pile end condition which is very important factor for pile behaviour. To verify the applicability of HWAW method in non-destructive test for pile, the numerical simulation test using ABAQUS was performed. And the model pile was made and the proposed non-destrcutive pile tests were applied to evaluate soundness and end boundary condition of model pile in the air and soil box. Through a numerical simulation and model tests, it is shown that the HWAW method has good potential of applying to the evaluation of pile integrity.
