摘　　要：结合广东省佛山市G325九江大桥加固工程实例,介绍了斜拉桥换索、调索设计基本思路、施工顺序及监控情况,提出了增量法换索、调索的设计理念与验证办法,并阐明了尽可能用最小的索力调整值和最少的调索数达到目标线形并有效降低调索风险的调索基本原则。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.
