Abstract：
The structure of railway cable-stayed bridge is more complex than common bridge. If the structural shape and internal force error couldn't be adjusted timely, final state of cable-stayed bridge will greatly deviate from target. Considering that the open-loop control method can't meet the accuracy for construction of large steel truss span cable-stayed bridge, it's necessary to research the fine control technology for cable-stayed bridge construction. Based on the analysis of construction difficulties and countermeasures for one greatly deviate from target, fine monitoring system for construction was designed and researched. Then, each typically stage of bridge construction was simulated by this system. Through the project results, we can know that the theoretical predictions are closed to the measured value, which will provide reference for the similar engineering construction.
