| Abstract: | In view of the challenges for the construction of super-long-span hybrid girder cable-stayed bridge, a whole- procedure construction control based on geometry control method is proposed. In this study, a better construction control system is established, which can ensure the internal force and geometric profiles in completion stage to meet ideal requirement. Construction experience indicates that the theoretical calculation is in well accordance with the field results, which can provide a reference for the similar bridge construction control. |
