多波速测深系统在水电站泄洪消能建筑物缺陷检测中的应用

Application of Multi-beam Sounding System in Defect Detection of Flood Discharge and Energy Dissipation Structures in Hydropower Stations

通过对多波束的基本原理、系统组成等方面进行分析,对某水电站坝下泄洪消能建筑物中的冲刷破坏进行检测,以确定其混凝土冲刷破坏程度。工程检测结果表明,多波束测深系统具有适用性广、效率高、成像清晰等直观的技术优势,对水下结构隐患的识别给予了一种可行、便利的方法和途径。作为一种全新的海洋探测技术,在引入水电领域的过程中也暴露出了问题,但随着技术的不断进步将会得到妥善解决。

With an analysis of the basic principles and the system composition of the multi-beam technology,the application of the multi-beam sounding system in a hydropower station is introduced,which is to detect the erosion damage of the flood discharge and energy dissipation structures under the dam,especially the extent of the erosion damage of the concrete.The inspection results show that the multi-beam sounding system is of obvious technical advantages such as wide applicability,high efficiency,and clear imaging,providing a feasible and convenient approach for identifying underwater structural hazards.As a new ocean exploration technology,problems are also exposed during its introduction in hydropower industry.With the continuous development of the technology,the problems will be properly solved.
