摘要
缆索由钢丝 (或钢绞线 )制作而成 ,广泛应用于大跨度桥梁和建筑中。由于跨越江河湖海和在应力条件下工作 ,应力和腐蚀的作用直接影响缆索的使用寿命。介绍了钢丝的制作和质量控制特点 ,分析钢丝腐蚀和断丝的原因和影响 ,探讨缆索断丝和锈蚀问题的防护、检测和处理。
A cable is made of high strength steel wires(or strands),which is widely used for long span bridges The service life of the cables is affected directly by the stresses and corrosion due to their crossing over rivers or seas and work at stress conditions The fabrication of steel wires and the features of quality control are introduced;the causes of corrosion and break of the steel wires as well as their influence are also analyzed At last the protection,detection and treatment of the corrosion and break of the wires for cables are discussed
