Assessment of In-Situ Conditions Using Wave Propagation Techniques
Abstract
The overall objective of this research is to stimulate the development of wave propagation sensor techniques for the evaluation of in-situ conditions. Assessment of conditions in the built environments is critical to the management of infrastructure, and there are significant opportunities for developing such sensor technology which have yet to be fully exploited. This research has been directed towards providing a development framework, and an associated set of developmental tools, applicable to wave propagation techniques. Such techniques include seismics, sonics and ultrasonics, and impulse radar. The research has focused on the development of tools in two areas: (1) predictive analytic models and waveform synthesis techniques, and (2) laboratory evaluation techniques. The development of these tools has been specifically oriented towards applications involving identification, location, and characterization of regular and irregular subsurface anomalies. Originally this research was conceived in an effort to exploit commonalities between electromagnetic and mechanical wave propagation techniques. As we discussed in the summary of findings, this perspective was found to be too broad at this stage of the research. Such a perspective will be more meaningful when a better understanding of specific properties of the media is achieved. Keywords: Non destructive testing; Wave propagation; Sensor techniques; Infrastructure assessment and management; wave form synthesis techniques.
