Reflection wave method is a common approach to detect the foundation pile. However, if it is applied to the integrity test of pre-stressed pipe pile, the test results may vary with the pile-soil conditions. To evaluate the reliability on the application, this paper designs model piles with different degrees of defects, and tests the integrity of these piles at different stages. Through the analysis of the test curves, a large discrepancy was found between the pre- and post-sinking defects of the pre-stressed pile piles, indicating that the pile-soil conditions have a major impact over the defect causes and the limitations of the reflected wave method.
