Study on Design Method of Diversion Pier in Channel Entrance Area with Complex Flow Characteristics

Abstract

The entrance area is the main way for ships to enter and exit the approach channel. During the navigation period, the approach channel, the entrance area and the connecting section should avoid turbulence, whirlpool and other bad flow conditions. When conditions are limited and cannot be avoided, engineering or non-engineering measures should be taken to make it harmless to ensure the efficiency and safety of shipping. Aiming at improving the navigation safety effect of the estuary area, this paper analyzes the effect of improvement measures under the actual navigable flow condition by establishing the flow information fitting model and the prediction model of diversion pier setting, and provides the design method and basis for the installation of diversion pier in the estuary area to be predicted. It enriches the model base and knowledge base of the channel entrance area with complex flow characteristics, which has important practical significance and engineering value for shipping safety and waterway management.
