[0002] Bridge cables are the main load-bearing components that directly transfer the weight of the main beam and bridge deck of a cable-stayed bridge to the tower. Cables of cable-stayed bridges are usually made of steel cables, which can be composed of parallel steel wires, parallel steel cables, single steel cables, wire ropes, closed steel cables or solid steel bars according to their composition methods. During the service process, the bridge structure is affected by various internal and external factors such as design standards, construction quality, material degradation, traffic loads, extreme loads and accidental accidents. If the structural safety cannot be fully guaranteed, there will be safety hazards. In order to ensure the safe service of the bridge, it is necessary to use physical damage detection auxiliary devices to conduct regular safety inspections of the bridge.
