Response Testing

The impulse response method has been applied to the integrity testing of piles for many years and constant velocity one-dimensional (1D) wave theory is conventionally used to interpret the test results. However, there are three-dimensional (3D) effects in the wave responses of piles, so this research uses 3D guided wave theory to analyse the impulse response results. This proposed approach is verified on five piles with different diameters and lengths. The resulting analysis indicates that guided wave theory can efficiently identify the phase velocities at their corresponding resonant frequencies, which are found in the testing spectrum using the concept of resonance. The measured phase velocity is mostly predictable within ±2% along the theoretically determined curve, with velocity slightly reducing as frequency increases.
