Research on the application of underwater topographic survey technology in port dredging engineering
Ports occupy an important position in social and economic development.Doing a good job in the construction and maintenance of the port can improve the level of social economy.Therefore,this paper takes the first phase of the dredging project of the west port basin of the embracing port basin PPP project in the Lvsi port area as an example to analyze the application of underwater topographic survey technology in port dredging engineering.application.From the analysis results,it is necessary to do a good job in equipment selection,reference station layout,water level monitoring,data acquisition and data processing when applying underwater topographic survey technology in port dredging projects.At the same time,it is necessary to control the error of underwater terrain measurement by correcting the swaying attitude of the hull.
