In this paper, part of the results extracted from the consultancy project of applying GPR for pier structure diagnosis is presented. GPR survey results on pier structures of: (1) a 9m × 4m slab and (2) the side (8m × 0.35m) of a beam located at Macau Ferry Terminal, Hong Kong are discussed. This study is a preliminary study on constructing work flow of defect characterization; and the GPR results...
This paper presents a new approach to evaluate corrosion of reinforcement in concrete by ground penetrating radar (GPR). Pulse GPRs were used to monitor the continuous corrosion process in concrete, in which the changes of amplitudes, travel times and short time fourier transform (STFT) spectrograms associated with the bar reflections were continuously measured. The yearly long corrosion process of...
