The invention discloses a composite precast concrete rail plate. The composite precast concrete rail plate comprises rail plates and rail bearing platforms at the upper parts of the rail plates, wherein self-compacting concrete filling holes penetrating from top to bottom are arranged in the middle parts of the rail plates; door-type steel bars are arranged at the bottom parts of the rail plates and are embedded in self-compacting concrete layers fixedly connected with the bottom parts of the rail plates; and embedded shear plates are arranged at two ends of each of the rail plates. The composite precast concrete rail plate has the beneficial effect that the rail plate is suitable for any section of high-speed rails and metros. Due to the arrangement of the door-type steel bars and the self-compacting concrete layers, equivalently the structural thickness is increased indirectly and the temperature stress and bridge deflection force resistant capabilities are enhanced; the embedded shear plates are arranged at the two ends of each of the rail plates, so that the rail plates can be connected in sequence in construction, and the shearing force between the rail plates can be well transferred; and therefore, the problem of unsmooth rails due to non-uniform settlement of road foundations is well solved.
