Based on the basic principle of reflection and transmission in the process of the propagation of logitudinal wave, this paper recounts a new theory and method for the application of pile body completeness inspection data with reflection wave method to the quantitative determination of apparent reflection coefficients and the round travelling time of reflection wave.
