多波束测深系统在码头安全监测中的应用

Application of Multi-Beam Sounding System in Wharf Safety Monitoring

摘要: 多波束测深技术使用多通道的声呐系统测量船体下方及两侧大范围的水下深度，是一种能高效、高精度、高分辨率获取水底地形的新技术，在水下地形测量等领域得到了广泛应用。本文通过多波束测深系统对选定码头前沿区域水下地形进行多频次监测，经过测量、数据处理和与单波束测深进行精度对比分析等步骤，得到目标区域三维地形图，并通过两次的数据进行对比分析，研究了该码头前沿河床经抛石保护后的冲淤变化，为码头的安全管理提供充分合理的数据依据。

Abstract: Multi-beam sounding technology uses multi-channel sonar system to measure the underwater depth under and on both sides of the ship hull. It is a new technology that can obtain the underwater topography with high efficiency, high precision and high resolution, and has been widely used in the field of underwater topography survey. In this paper, multi-beam sounding system is used to carry out multi-frequency monitoring of the underwater terrain in the front area of the selected pier. After measurement, data processing and precision comparison analysis with single beam sounding, three-dimensional topographic map of the target area is obtained. Through comparative analysis of the two data, the erosion and deposition changes of the riverbed at the front of the pier after being protected by rubble are studied. It provides sufficient and appropriate data basis for the safety management of the terminal.
