(57) The invention discloses a prestressed steel-concrete bearing platform structure of a continuous rigid frame bridge and a construction method of the prestressed steel-concrete bearing platform structure, and belongs to the technical field of bridge construction. The steel-concrete combined section is arranged at the bearing platform, so that the part above the bearing platform of the bridge adopts a steel structure form with light self weight and various shapes, the subsequent construction efficiency of the bridge is improved, the foundation load is reduced, and the foundation concrete consumption is saved. During construction of the steel-concrete bearing platform, the installation precision of a super-large bearing platform steel structure is ensured through reasonable construction machinery and measures, the steel-concrete bearing platform adopts a prestress construction technology, cracks can be avoided, the overall tensile strength of the bearing platform is improved, and the bearing capacity of the bearing platform is improved.
