Research of the echo-impulse method of control of drilled pieces

Abstract: The results of field and computational experimental studies of the pulse-echo method are presented. Typical reflectograms of bored piles are presented. The factors that complicate the interpretation of control data are noted. An analysis of the formation of the fronts of an acoustic pulse during its shock excitation is presented. Estimates of the influence of reinforcement on the estimates of the propagation velocity of an acoustic pulse are given.
Keywords: non-destructive testing, pulse echo method, bored piles, pile length, geological profile, wave modeling, reinforcement
