水下抛石高精度准实时多波束处理系统的研发与应用

Development and application of high-accuracy and quasi-real-time multibeam processing system for under-water rock dumping construction

针对水下抛石施工的测深系统不能实时反馈数据处理结果的问题,对多波束测深系统的自动滤波功能进行研发,采用CUBE滤波算法,实现了多波束测深数据的准实时处理以及抛石断面与设计断面的对比分析,并将其应用于某深水防波堤实际工程。结果表明,该系统能够对水下抛石施工起辅助决策的作用,并提高水下抛石效率和精度,可为类似工程提供参考。

Aiming at the problem that the depth measurement system of under-water rock dumping construction cannot provide the real-time data processing results,we develop the automatic wave filtering function of multi-beam depth measurement data processing system with CUBE algorithm,and achieve that the quasi-real-time processing of multi-beam depth measurement data is provided,as well as the actual rock dumping section compare with design section.We apply this system in a case of deep-water breakwater construction.The results show that the system can play an assistant decision-making role in underwater rock dumping construction,and improve the efficiency and accuracy,which can provide references for the similar projects.
