description The invention discloses a supporting seat type fabricated ballastless track structure. The top of under-railway foundation is paved with a reinforced concrete base. A supporting seat system is arranged on the reinforced concrete base, a track slab is laid at the top of the supporting seat system, and a rail is fixed on the track slab through a fastener system. According to the supporting seat typefabricated ballastless track structure, a traditional consolidated structure is replaced by a fabricated structure, that is, the track slab and the reinforced concrete base can be conveniently separated; high flatness of the top surface of a supporting seat can be precisely achieved by adjusting cushion plate, and the track slab can be directly laid; and an isolation layer is replaced by the supporting seat system, that is, the point-type supporting seat system consisting of the supporting seat, the adjusting cushion plate and a supporting set base plate enable flatness of the top surface ofthe supporting seat to be
