The invention discloses a floating-dock-type multifunctional floating wharf, which comprises a steel pontoon (1), a steel approach bridge (2), anchoring systems, mooring systems, a fixing crane (5), asemi-concave dock and a high-pressure air system. The steel pontoon (1) is connected with a wharf body (14) through the steel approach bridge (2), and the anchoring systems are fixed to the two endsof a bow and a stern of the steel pontoon (1); and the mooring systems are fixed to the two sides of the steel pontoon (1), and the fixing crane is fixed to a middle deck of the steel pontoon (1). According to the floating-dock-type multifunctional floating wharf, the functions of wharf berthing water front increasing and movable ship dock repair are both achieved, and the floating-dock-type multifunctional floating wharf has flexibility, high efficiency, multi-purpose performance and non-destructiveness to surrounding sea areas and thus has good application and popularization prospects.
