| Abstract: | Through CFG pile testing for a subgrade and the collecting and processing of wave form, the comparison with the pile defects were carried out, thus the correspondence between typical defect type and wave form was summarized. This paper suggested to, in CFG pile testing by low strain reflection wave method, pay attention to the method handling pile head and the influence of selection of excitation wave spectrum on wave form collection, which is taken as the reference in the practical application. |
