| 摘要： | This report describes work on laboratory and field performance reviews of an ultrasonic Quality Assurancedevice called MIRA for application to plain and reinforced concrete infrastructure components. Potential applications investigated included bridge deck delamination detection, deck thickness profiles, and detection of internal steel bars and dowels. Based on the observed performance of the unit, three classification categories of applications were defined: field ready, potentially ready, and challenging. In general, the MIRA device is not well suited to provide full-coverage rapid scans over an entire structure. Rather MIRA is more suited for targeted inspection or failure analysis to determine general geometric and internal features of concrete elements because MIRA is able to be quickly deployed for spot inspections with little site preparation. A user’s manual was produced to assist in introducing new users to the proper operation and interpretation of the MIRA device. |
