Study on construction control technology for tower and beam synchronous construction of cable-stayed bridge

With beautiful appearance, large span capability, and reasonable load conditions, cable-stayed bridges have been constructed widely. In this paper, combined with the specific circumstances of the project of the Dingzihekou Bridge, the construction control technology for tower and beam synchronous construction is studied. The construction method was discussed from the aspects of the influence factors, control principle and application scope of the tower girder synchronous construction. The whole, main tower, main girder, stayed cable and other control measures are put forward to ensure the reduction of construction error.
