| Abstract: | In combing with the engineering practice on reinforcement for Jiujiang Bridge on National Highway 325 in Foshan City of Guangdong Province,this paper firstly introduces the basic concept,construction procedure and monitoring situation for cable change and cable adjustment.And then it proposes a design concept of Increment Method and its verification for cable change and adjustment.Last,it illustrates the cable adjustment principle which is using the minimum cable adjustment force and the least number of adjusted cables to reach the target alignment as well as to reduce the cable adjustment risk as far as possible. |
