Research on Cable Replacement Design Method for Concrete Cable-stayed Bridge
Due to the evolution of material properties and changes in operating loads,the cable performance of cable-stayed bridge with double towers and double cable planes changes,which in turn affects the normal service performance of the bridge.In order to ensure the structural safety of cable-stayed bridge,it is necessary to replace the cables that do not meet the design requirements in time.Based on this,this paper takes Huaihe River Bridge on Jiefang Road in Bengbu City as the engineering background to expound the cable replacement design method of the double-tower double-cable plane cable-stayed bridge from the technical status of the stayed-cable,the cable replacement design scheme,and the key cable replacement design points based on the survey results of the technical status of the bridge stayed-cable.The research results of this paper can provide reference for cable replacement engineering of cable-stayed bridge.
