| Abstract: | For the complexity of structural and mechanical behavior of thousand-meter-scale cable-stayed bridge, the construction presents its own challenges. In this study, a hybrid girder cable-stayed bridge in China with a main span of 926 m is used to examine the control of unstressed cable length during the fabricating and tensioning construction stages on the basis of geometry control method. Finally, put forward corresponding quality control measures, providing a reference for similar bridge construction. |
