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

摘要: 阐述了物探检测技术在大坝缺陷检查中的应用,分析了目前物探检测技术应用的局限性,展示了高精度三维实景建模、混凝土三维超声波、适应性ROV等新技术,这些技术在检测中更有优势,且效果理想。最后,对大坝缺陷检查中物探检测方式、成果展示模式、成果管理等方面进行了展望。
