An experimental study on the integrated health monitoring of PHC pile foundations is presented using vibration and wave measurements. The health monitoring is divided into two stages: damage detection before and after excavation. The damage detection before excavation is intended for estimating the damage globally by vibration generator and acoustic emission tests, whereas the damage detection after excavation is for estimating the damage locally by impact hammer and ultrasonic wave tests. To simulate the evolution of pile damage, the cyclic loading test of a PHC pile specimen is performed. During the successive loading cycles, four damage detection tests, i.e., vibration generator, impact hammer, acoustic emission and ultrasonic wave tests, were carried out. Based on the experimental results, the usefulness and limitations of the proposed damage detection scheme are discussed.
