ADVANCED TECHNOLOGIES FOR DESIGN INFORMATION VERIFICATION

摘要

This paper discusses several technologies that have the potential to enhance facilities design information verification. These approaches have shown promise in addressing the challenges associated with the verification of geometry and material composition for structures that are not directly accessible for physical inspection. A simple example is a pipe that extends into or through a wall or foundation. Both advanced electromagnetic and stress wave modalities will be discussed. These include advanced radar imaging, transient thermographic imaging, and guided elastic waves. Examples of current applications are provided. The basic principles and mechanisms of these inspection techniques are presented along with the salient practical features, advantages, and disadvantages of each technique. Other important considerations, such as component geometries, materials, and access are also discussed.
