The feasibility of detecting damage at the steel pile-clay interface using cylindrical guided waves is investigated in this paper. It is shown that cylindrical guided waves (or cylindrical Lamb waves) can easily detect such damage. A special coupler between the steel pile and ultrasonic transducer has been used to launch non-axisymmetric (or flexural) cylindrical guided waves in the steel pile. This investigation shows that the cylindrical guided waves can propagate along the steel pile embedded in clay and are sensitive to the interface damage between pile and clay.
