三维成像声纳技术在水下结构探测中的应用

由于受到水利工程水下工作环境的制约,常规的隐患探测方法很难实现对水下工程安全隐患的准确探测,本文在对常用水下探测技术(设备)及其应用发展情况进行探讨的基础上,介绍了三维实时声学成像声纳系统基本功能,并在岩石岭水库和坎门渔港防波堤对该系统的功能和效果进行了探测。结果表明:该系统可以快速、准确地对水库、海塘(堤防)等水利工程水下结构进行安全隐患探测,实时生成连续、清晰的三维图像,且具有较强的适用性,可以为水利工程建设和安全运行管理提供数据参考。

Application of three-dimensional imaging sonar technology in detection of underwater structure

Due to the restriction of work environment of water conservancy engineering underwater, the conventional hidden danger detection methods are difficult to achieve accurate detection of safety hidden danger of underwater engineering.On the basis of discussion on common used underwater detection technology (equipment) and application development, this article introduced the basic function of three-dimensional real time sonar imaging system,and practiced the technology in Yanshiling Reservoir and Kanmen fishing port breakwater.The result shows that the system can quickly and accurately detect the underwater safety hidden trouble to water conservancy project such as reservoir, seawall (dike),and can generate continuous and clear three-dimensional image,and has stronger applicability and can provide the data reference for the construction,safety operation and management of water conservancy.
