| Abstract(in English) | Recently, deterioration of social infrastructure such as tunnels and bridges has become a serious social problem. It is required to properly and rapidly detect for abnormal parts of the social infrastructure. The ground penetrating radar (GPR) is efficient for the social infrastructure inspection. However, it is difficult to detect for an air gap under a reinforced concrete by the GPR because the electromagnetic wave is complexly scattered to many reinforcing bars. In this study, to objectively and quantitatively inspect for a social infrastructure using the GPR, we have analyzed characteristics of detection for abnormal parts under reinforced concrete using the GPR by a fast finite-difference time-domain (FDTD) simulation with graphics processing units (GPUs). |
