Abstract: This paper introduces the application of geophysical detection technology in inspection of concrete defects and analyzes its limitations. As well, new technologies have been presented such as high-precision three-dimensional scene modeling, concrete three-dimensional ultrasound, adaptive ROV and so on with more advantages and ideal effect. Finally, the further development in aspects such as geophysical detection modes, results display modes and results management are discussed.

Key words: geophysical detection, concrete defects, underwater detection, dam seepage
