Ground platform structure and construction method thereof

The invention discloses a ground platform structure and a construction method thereof, and belongs to the field of ground platform structure design. A main body structure of the ground platform structure can be quickly formed through combined arrangement of structures such as a foundation layer, foundation connecting beams, retaining walls, short columns and structural beams, and then a plurality of prefabricated plates are sequentially laid on the main body structure, a platform plate of the platform structure can be rapidly formed, and then arrangement of the ground platform structure is achieved. The ground platform structure is simple in structure and convenient to construct, construction of the ground platform structure can be rapidly achieved, the ground platform structure is particularly suitable for application scenes where the distance between the platform and the ground or the rail surface is small, the platform structure construction stability can be guaranteed, meanwhile, the influence of platform
