Abstract To establish a relationship between wave velocities in concrete pile shaft measured respectively by the ultrasonic
wave method and low-strain reflected wave method, a simplified formula for the ratio of wave velocity in infinite medium to
that in one dimensional bar was proposed herein by use of the Kelvin-Voigt viscoelastic theory. It was shown by theoretical and
experimental studies that the ratio of ultrasonic wave velocity to times of low-strain reflected wave velocity ranged
among ~, which decreased with increasing of the age, Young’s modulus
