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.展开更多
