Provided is a thickened frame type ballastless track plate. The track plate comprises a base plate, bosses and track bearing tables. The base plate is of a cuboid, the two bosses are symmetrically arranged on one face of the base plate along the axis of the cuboid in the length direction, and the track bearing tables are evenly distributed in the length direction of the upper surfaces of the bosses. A through hole is formed in the base plate and is located between the two bosses symmetrically arranged on the base plate, and a frame structure connected between the two bosses through a transverse reinforcement concrete structure is formed. The thickened frame type ballastless track plate can effectively reduce track plate warping caused by temperature stress, eliminate a pull cracking phenomenon, and enhance running safety and comfort. The thickened frame type ballastless track plate is reasonable in structural stress, light, high in structural strength and capable of effectively improving the stress condition of a sleeper structural system, prolonging the service life of the structure and optimizing rack circuit parameters, improves the circuit transmission characteristic of a resonant track, can be directly and effectively connected with a current high-speed railway CRTS-I ballastless track plate, and is suitable for industrial production.
