Summary:The invention discloses a construction method of prefabricated prestressed plates of an assembled underground station. Middle plates and top plates of the assembled underground two-layer station are of an integral reinforced concrete floor structure formed by overlapping and cast-in-place of the prefabricated prestressed plates. The thickness of each prefabricated prestressed plates is about halfof the thickness of a floor, inverted-T-shaped rib plates are adopted, prestressed steel strands are arranged in ribbed beams, prestress is applied through a pre-tensioning method, the prefabricated prestressed plates are hoisted and placed on a sliding platform car flatwise, the sliding platform car can walk on a single-side prefabricated overlapped outer wall plate and a semi-prefabricated overlapped beam side bracket beam, the prefabricated prestressed plates are efficiently moved to the mounting position through the sliding platform car, cantilever beams are adopted to lift the prefabricated plates, the sliding pl
