Research on Velocity Monitoring Technology in Complex Water Environment of Waterway Renovation Buildings
After the implementation of the Changjiang waterway project,it is necessary to monitor the flow velocity in the area of the remediation buildings.The waterway remediation buildings generally have fast flow rates and complex water flow patterns,and the flow patterns and flow rates have a particularly serious impact on the remediation buildings and surrounding terrain changes.Therefore,in the analysis of the damage trend of the remediation building,the surrounding flow state is one of the factors that must be considered.At present,there are very few researches on the monitoring technology of water flow velocity in the area of waterway renovation buildings.In this paper,the GNSS+ADCP data fusion technology is used to measure the absolute velocity of the ship through on-board RTK,and the relative velocity measured by ADCP is combined to calculate the absolute velocity of the water body which greatly improves the flow velocity observation accuracy of ADCP,and can provide a new way for flow velocity monitoring in the complex water environment of waterway remediation buildings.
