Abstract:Based on the defect determination technology of ultrasonic testing pile integrity, main problems of the current determination technology were pointed out, such as low utilization rate of ultrasonic signal, unintuitive defect determination, and multiple non-uniform acoustic parameters. Methods to make full use of digital processing and application of information technology of ultrasonic testing data and waveform information, defect determination technology with a variety of acoustic parameters combined and three-dimensional imaging display technology were put forward, which make the ultrasonic detection more accurate and reliable in determination of pile defect and make the results more intuitive and clear. It is conducive to the popularization and application of ultrasonic method.

Keywords:ultrasonic method; pile integrity; comprehensive factor determination method; three-dimensional imaging
