Interlayer Slide Detection Using Piezoceramic Smart Aggregates Based on Active Sensing Approach

Interlayer slide is a common type of damages in geological and civil engineering. Interlayer slide damage is an internal cause of landslide and collapse, which may further result in catastrophic losses. It is desirable to develop a real-time monitoring system that is able to detect this kind of damage. In this paper, an experimental feasibility study on interlayer slide detection using piezoceramic smart aggregates based on the active sensing approach was performed. A mortar specimen, sandwiched with a weak interlayer, was fabricated before conducting the loading test. Two pairs of smart aggregates were installed at specific positions inside of the formwork before pouring the mortar. With the embedded piezoceramic patch transducers, the smart aggregates possess both the actuation and sensing functions. Two smart aggregates were employed as actuators, which generated the stress wave to propagate through the weak interlayer. The other two smart aggregates were used as sensors to receive the wave responses. In addition, a wavelet packet analysis was applied to develop a damage index to assess the initiation and development of the interlayer slide. Experimental results show that the proposed method was able to detect the interlayer slide damage.
