Based on the theory of ultrasonic nondestructive testing, a prediction method for the strength of concrete structures using ultrasonic testing was established. The predicted strength of concrete with 4200 measuring points using ultrasonic testing and measured strength of concrete with 400 samples using field drilling for core tests were compared based on the background of Wusong Jetty. The results show that both of the predicted and measured strength are approximate normal distribution. The probability peak intervals of the two methods are 12 to 16 MPa and 9 to 15 MPa, the distribution density are 28% and 23.26%, the range of strength distribution are 3 to 25 MPa and both are smaller than the design value. These results show an overall good performance by the prediction method.
