Abstract
Cable bridges have become the first choice for large-span bridges among modern bridges because of their advantages such as large span,material saving,appearance,earthquake resistance,convenient construction,low maintenance costs,strong adaptability and small environmental impact.After the bridge is completed and put into operation,as its service life increases,due to various aspects such as design,construction,and maintenance,various damages and degradation phenomena will occur during the use of the bridge suspenders and cables.These diseases will affect the structure of the bridge.Safety and service life pose safety hazards to bridge operations.Based on the results of special inspection work on suspender and cable in recent years,this paper summarizes the common diseases and inspection methods of suspender and cable structures,analyzes the causes of suspender and cable diseases,and proposes waterproofing modification methods for suspender and cable,providing reference for inspection and maintenance of similar structures.关键词
