Abstract

Bridge pier foundations in water areas are eroded by different forms such as water scouring, so fast and effective underwater detection technology is required for evaluating the erosion state of the pier foundation and the reinforcement effect.For the underwater sonic imaging method, acoustic emission was used to excite the seismic source, and elastic wave signals were collected simultaneously by a multi-point underwater acoustic detector, realizing rapid detection of complex water environment.Based on the propagation characteristics of elastic waves in the complex media, the elastic wave waveform data of the acquisition profile was extracted, and the change of elastic wave reflection intensity was judged by using the image recognition method.Firstly, the propagation characteristics of elastic waves in complex media were simulated using numerical simulation, and information such as the riprap position range was identified based on the image characteristics of elastic wave reflection strength and waveform travel time.Next, on this basis, on-site testing of riprap countermeasure to bridge foundation was carried out, and the underwater riprap spatial distribution was obtained by combining the multi-beam scanning and the three-dimensional visualization method.Finally, the test results were compared with the actual backfill amount, and the effectiveness of the underwater acoustic imaging method was verified.

Key words： riprap countermeasure to bridge foundation underwater sonic imaging method image recognition multi-beam scanning three-dimensional visualization
