The invention relates to a self-compacting concrete prefabricated hollow plate girder with hybrid fibres instead of reinforcing steel bars and a manufacturing method. The reinforcing steel bars comprise pre-stressed reinforcing steel bars, ribbed steel bars and plain round reinforcing steel bars; the pre-stressed reinforcing steel bars comprise pre-stressed tensile reinforcing steel bars; the ribbed steel bars comprise ribbed longitudinal tensile reinforcing steel bars, ribbed longitudinal compressive reinforcing steel bars, ribbed web plate longitudinal force bearing reinforcing steel bars, and ribbed anti-shear stirrups; the plain round reinforcing steel bars comprise top erecting reinforcing steel bars for fixing the stirrups; the concrete is high-performance self-compacting concrete with the compressive strength of not greater than 50 MPa; the fibres are reinforcing and toughening crude fibres which are mixed in the self-compacting concrete, and comprise end part bending hook-type steel fibres, steel wire-simulated synthetic crude fibres or basalt fibres; the lengths of the fibres are not smaller than 3 cm, and the diameters are not smaller than 0.4 cm. The self-compacting concrete prefabricated hollow plate girder with the hybrid fibres instead of the reinforcing steel bars has the advantages that the concrete shrinkage is small; cracks are reduced; the bonding stress of the concrete and the reinforcing steel bars is high; honeycombs, pitted surfaces and cavities are avoided; the distance between the stirrups is increased; the reinforcing steel bar arrangement precision is improved; the component durability is improved.
