| Abstract: | The forces of long-span cable-stayed bridges are an important symbol for determining whether the bridges work well. In this paper, the methods and principle of cable-forces monitoring for long-span cable-stayed bridges are introduced. And then, combined with the Wujiang Second Bridge, the mo-nitoring system and design of monitoring for cable-forces are ex-plained. Finally, cable-forces＇ monitoring results of The Wu-jiang Second Bridge are analyzed. Therefore, healthy evaluation for cables can be conducted and it is the basis of further evalua-tion for the whole bridge. |
