| Abstract: | Ultrasonic transmission method in pile testing process,due to various reasons,an error to judge the nature of defects may be made;missing judge,miscarriage of justice and given a heavy,lenient sentence are occurred.With the PDI＇s CHAMP pile in the actual review process of the emergence of some miscarriage of justice causes the phenomenon was elaborated and proposed to avoid methods to improve the detection accuracy. |
| Keywords: | ultrasonic wave cast-in-place pile ultrasonic testing pile test Defect |
