摘要
本研究主要介绍了多波束三维声呐系统水下检测的原理及方法,结合工程实例,对某桥基础冲刷状况进行了检测.通过与蛙人摸探成果的对比,验证了SONIC 2020多波束三维声呐探头在浅水检测中的准确性.结果表明:该系统可准确探测桥梁河床地形地貌、水下基础外观、水下基础冲刷等情况,其与传统水下检测技术相比,多波束三维声呐检测技术具有检测精度高、周期短、过程安全等优势,研究结果以期为类似浅水基础冲刷检测工程提供参考.
Abstract
The research mainly introduces the principle and method of underwater detection of multi beam 3D sonar system,and combines engineering examples to detect the scouring condition of a certain bridge founda-tion.By comparing with the results of frogman probing,the accuracy of SONIC 2020 multi beam 3D sonar probe in shallow water detection was verified.The results showed that the system can accurately detect the terrain and topography of bridge riverbed,underwater foundation appearance,and underwater foundation erosion.Compared with traditional underwater detection technologies,multi beam 3D sonar detection technology has advantages such as high detection accuracy,short cycle,and process safety.The research results are expected to provide reference for similar shallow water foundation erosion detection projects.
