Sutong Yangtze Highway Bridge is the longest span cable-stayed bridge completed in the world nowadays. The construction of superstructure of the main bridge was composed of several stages including erection of big block girders for side span, assistant span and tower area, erection of standard girders and middle span closure. The big block girders were hoisted as integer by floating crane. The standard girders were hoisted by double cranes system at the deck. Pushing assistant method was adopted in middle span closure construction.An all-stage self adaptive geometry control method was used in the construction process. By all-step accurately control to unstressed dimension and shape of all structure components and realization that control system and controlled system adapt to each other, the goal to make the final line shape and inner force of bridge structure under control could be achieved. Two solutions including based GPS and based total station dynamic geometry monitoring systems were used to resolve the measure problem under the condition that wide–range wind-induced vibration with long cantilever state. Finally, the research on wind-induced vibration of super structure during the construction period was executed. Buffeting response analysis to the longest single and double cantilever state were carried out. The analysis and evaluation to wind resistant safety of main girder at the longest single cantilever state were made, and the corresponding wind resistant measures were suggested. As built geometry error and cable force error were controlled in a range design required.
