【 摘 要 】

Based on the limitation of the conventional methods to the detection of visible damages underwater to the hydraulic structures, along with the characteristics of the visible damages, we suggest the application of Dual-frequency Identification Sonar technology for its detection. This paper illustrates how Dual-frequency Identification Sonar technology works and puts forward the method of detection. The application of Dual-frequency Identification Sonar technology has been carried out in engineering practice and the result indicates that the technology performs well in the detection of visible damages underwater to the hydraulic structures.
