In order to further understand the characteristics of longitudinal grouting compactness, this paper develops a stress wave based active sensing approach using piezoceramic transducers for monitoring the longitudinal grouting compactness of the curve tendon ducts. Experimental results show that in the no grouting, 50% grouting, 75% grouting, and 90% grouting conditions, the sensors cannot receive any stress wave. Only when the actuator and the transducers are grouted fully, the transducers can receive the stress wave propagated by the actuator. The wavelet packet-based energy analysis was adopt...
