A certain project is located in an open sea area with complex terrain,complex tidal characteristics,and large changes in wind,waves,and water depth below the dock.To meet the safety of ship berthing and disembarking under such complex port construction conditions,a hybrid structure combining closely arranged diversion piles and high pile docks is adopted.The application effect of this new structure is verified through physical model tests of tidal currents,waves,and mooring,and the standards for mooring and berthing operations are determined.The experiment shows that this structure can effectively improve the flow state and reduce the cross flow intensity.At the same time,the diversion effect can be changed by adjusting the spacing between the diversion piles,reducing the engineering investment.The overall stress of the new dock structure can fully utilize the functions of each part,improve the hydrological conditions of the dock front water area,and achieve a balance between engineering technology and economy.The aim is to provide reference for the design of dock structures under similar complex port construction conditions.
