| 摘要： | The use of ground-penetrating radr (GPR) systems to investigate civil engineering structures has become a topic of great interest since the 1970s. Of particular interest is the use of GPR to detect deterioration in bridge decks. As of 1994, an estimated 40% of the 578,000 highway bridges in the United States were deemed structurally unsound due to deterioration in the upper layer of the bridge deck. The majority of deterioration takes place as the embedded reinforcing steel (rebars) in the upper layer of concrete corrodes, increasing the potential for the formation of planar cracks, or delaminations, between successive rebars. |
