A method for fabricating a wire strand from parallel steel wires for a main cable of a suspension bridge, the method including: 1) selecting and coloring a steel wire as a marking steel wire which is to be positioned at a vertex of a wire strand including a plurality of parallel steel wires and having an equilateral polygon section; 2) drawing position markers at positions of the standard steel wire corresponding to control points of splay cable saddles, center points of main cable saddles, middle points of side spans, a middle point of a middle span, and starting points of anchor heads of anchor spans of a suspension bridge; 3) relaxing and shaping coils of the steel wires to yield a prefabricated wire strand; 4) preforming the positions of the cable saddles; 5) coiling the wire strand including; and 6) casting anchor of the wire strand.

Method for fabricating wire strand for main cable of suspension bridge

A bridge intelligent cable system with a built-in fiber grating sensor is provided, which is applied in a cable bearing structure such as a cable-stayed bridge, a suspension bridge, and an arch bridge. The system includes an anchor cup, a wire dividing plate, a connecting cylinder, a fiber grating sensor, and a cable body, in which the fiber grating sensor includes a fiber grating strain sensor and a fiber grating temperature sensor, tail fibers of the fiber grating strain sensor and the fiber grating temperature sensor are led out, the packaged fiber grating strain sensor is fixedly connected to an outer-layer steel wire of the connecting cylinder, the packaged fiber grating temperature sensor is suspended on the steel wire of the connecting cylinder, holes are punched in the wire dividing plate, and a preserved steel pipe is buried in advance in the connecting cylinder and the anchor cup.
