The invention relates to a track panel design method based on a fiber bragg grating array, which comprises the following steps of: acquiring the disturbance condition of roadbed slab concrete on a track panel, specifically, arranging a disturbance monitoring optical cable on the track panel, and arranging the disturbance monitoring optical cable at a position, which is suitable for being coated by the roadbed slab concrete, of the track panel, the disturbance monitoring optical cable is a fiber bragg grating array stress optical cable integrated with a plurality of fiber bragg grating stress sensors; when the roadbed slab is poured, monitoring data of the disturbance monitoring optical cable are collected, and roadbed slab concrete buoyancy data borne by the track panel are obtained; obtaining current track panel rigidity data and roadbed slab concrete parameters, forming a corresponding relation among track panel rigidity, roadbed slab concrete parameters and roadbed slab concrete buoyancy data borne by the
