Numerical Study of Nondestructive Test of a Wharf Concrete Pile

The nondestructive test of a wharf concrete pile under a vertical impulse load next to the pile is simulated and analyzed.Then the signals that reflect integrity characteristics of the wharf concrete pile are obtained by signal processing,and the integrity of the wharf concrete pile can be judged.Finally,the simulated curves agree well with those obtained from field measurements.Consequently,the test method of the wharf concrete pile is correct and will play an important role in increasing the accuracy of nondestructive test of the wharf concrete pile.
