Cable is the main bearing component of long-span bridges, and their life is extremely important to the safety of the bridge. Mainly from two aspects of the corrosion and fatigue which influence the life of the cables, the paper puts forward assessment criteria and the corresponding evaluation standards for the service life of the bridge cables, studies the mechanism of corrosion and fatigue of the cables and destruction features, and discusses the reliability study of corrosion and fatigue of the bridge cables.
