A bearing structure for railroad track rails on a track bed, comprising several load distribution plates in a rigid material disposed side to side on the track bed, with each load distribution plate having a surface area and thickness predetermined in such a way that its first resonance frequency is greater than the first resonance frequency of the vibrations locally generated in the rails by the passage of the wheels of a vehicle on the rails. The different load distribution plates may advantageously be interconnected by joints allowing the pivoting of each load distribution plate with relation to adjacent load distribution plates. The load distribution plates may be placed on the ground of the track bed or on the foundation of a tunnel and they may also be integrated in the coating of a railroad way. The load distribution plates may bear rails of the railway track, switches and crossings, fixation systems on which the rails may be fixed or even ballast that itself bears cross ties on which the rails of the railway track are fixed.
