Wavelet Characteristic and Experimental Study of Pile Foundation Fracture

摘要

This paper analyzes reflection wave signals of pile foundation using wavelet theory, and proposes characteristic parameters of wavelet that show the integrity of pile foundation and the relation between pile foundation fracture and parameters of wavelet characteristic. The feasibility of analysis pile foundation using wavelet characteristic has been verified by experiments. The wavelet characteristic of pile foundation illustrates the extent and position of pile foundation fracture exactly.
