双频识别声纳技术在水工建筑物水下外观病害检测中的应用

Application of dual-frequency identification sonar to detection of underwater apparent defect of hydraulic structure

针对水工建筑物水下外观病害的类型特点,提出用双频识别声纳技术进行检测,并在工程实践中开展应用。实践表明,双频识别声纳技术对水工建筑物水下外观病害具有较好的检测效果,研究内容可为水工建筑物安全监测提供参考。

In accordance with the types and features of the underwater apparent defects of the hydraulic structures,the adoption of the technique of dual-frequency identification sonar for the detection of defect is proposed and then applied to the engineering practice concerned. The practice shows that better effect of detecting the underwater apparent defects of the hydraulic structures can be obtained from the technique of dual-frequency identification sonar,thus this study can provide some references for the safety monitoring on hydraulic structures.
