In view of the larger berthing water area of ramp medial,the more earthwork volume and the higher investment with mountainous river ro/ro sloping wharf of the ship’ s T-type berthing,considering the terrain,landform and water flow conditions,we analyze the mooring characteristics of the ro/ro sloping wharf by changing the T-type berthing angle,and propose a working form for the ship’ s declinate T-type berthing of the ro/ro sloping wharf.The comparison of engineering examples shows that the tilting of declinate T-type berthing can further reduce the width of the water area from shore side to ramp,meanwhile reduce the amount of engineering work and save the project investment,which can provide reference for other similar engineering design.
