ABSTRACT Based on the theory of tube wave propagation in a fluid‐filled borehole, this paper proposes a new method for detecting the integrity of pile foundation and overcomes some limitations of the existing pile integrity tests. The basic principle of detecting the pile integrity by the tube wave, testing equipment and concrete quality evaluation of piles are introduced. The feasibility of the tube wave detection for geological exploration of a bridge pile in a karst development area is verified by field tests. Through some test cases of prestressed high strength concrete pipe piles, cast‐in‐place piles and rock‐socketed piles with defects, the accuracy of the tube wave detection and other methods is compared. Then, some issues of the application of the tube wave for detecting pile defects are discussed. Finally, the content of this paper is summarized, and some suggestions on further research are put forward.
