The utility model relates to a track panel structure for a ballastless track, which comprises a plurality of sleepers connected in series and at least one disturbance monitoring optical cable which is a fiber bragg grating array stress optical cable integrated with a plurality of fiber bragg grating stress sensors. Each disturbance monitoring optical cable continuously extends in the longitudinal direction of the track panel and is arranged at the position, suitable for being wrapped by roadbed slab concrete, of each sleeper. According to the utility model, the disturbance monitoring optical cable is installed on the track panel, and the concrete buoyancy data of the track slab during the construction of the track panel is obtained through the disturbance monitoring optical cable, and whether the track panel and the track slab are safe or not is judged during the track operation; proper track panel rigidity can be conveniently selected according to factors such as roadbed slab concrete parameters during track
