The invention relates to a filling adhesive anticorrosion intelligent steel strand which is formed by a central wire and external steel wires which are wound around the central wire through twisted formation. The central wire is an elongated wire having a fiber and fiber grating sensor. The fiber and fiber grating sensor is distributed along the length direction of the elongated wire, and the fiber can be led out of the end part of the steel strand. Adhesive resin material is filled in the gap between the central wire and the external steel wires, and resin material is also coated at the periphery of the external steel wires. The central wire and the external steel wires are adhered together by the adhesive resin material so that harmonic force deformation of the central wire and the external steel wires is enabled to be truly realized without the phenomenon of wire slipping or wire dropping, repeated measurement and calibration of the sensor can be realized, the monitoring accuracy can be enhanced, the practical application problem of the project can be solved, the service life of the steel strand can be enhanced and the durability of the project structure can be guaranteed.
