多波束检测技术在长江深水航道和畅洲整治工程中的应用

针对长江南京以下12.5 m深水航道二期工程和畅洲标段深水、大流速工况下软体排检测、深水潜堤断面控制难题,进行多种水下检测方法的对比研究,首次将Sonic2024多波束检测技术应用于水下整治建筑物施工中软体排、深水袋装砂及水下抛石控制,通过测量得到高精度水下建筑物图像、位置和高程数据,实现了水下隐蔽工程可视化与定量化分析,起到较好的指导施工的作用。

Multi-beam detection technology in the Yangtze River deepwater channel Hechangzhou regulation project

To counter the problems in the Yangtze River 12.5 m deepwater channel phase II project Hechangzhou section soft mattress detection and cross-section control of deepwater submerged dike under conditions of deep water and large flow velocity,we compare multiple underwater detection methods,and apply the Sonic 2024 multi-beam detection technique for the first time to the control of soft mattress,deepwater bagged sand and underwater riprapping in the construction of underwater regulating works,by which,accurate data concerning the image,location and elevation of underwater structures are obtained and visualized and quantitative analysis of underwater concealed works are realized to guide the construction.
