Abstract: The invention discloses an optical fiber detection device with a steel rail as an elastomer and a railway overload and unbalanced load detection system, which solve the problems that strength of the steel rail is destroyed due to a joint style of a shear force detection device and the steel rail and an output curve can easily vary due to variations of an external force and temperature or man-made operation factors in the prior art. According to key points of the technical scheme, the optical fiber detection device comprises a shear force detection device, the shear force detection device comprises an optical fiber sensitive element which is fixed on a neutral axis of the steel rail through low-energy spot welding, the technical effects of outputting stable shear force waveform without being interfered by vibration of the steel rail and installation orientation convenient for polishing and welding are realized by virtue of arrangement orientation of the optical, fiber sensitive element, an optical fiber made of a new material is used for replacing an old material and being provided as a sensitive element, and a new combination technology with the new material as basis forms a metering and, measuring system.
