Cable-stayed rail transit bridge, geometry control, stress control,cable force control, field measurements
To guarantee the safety, durability and reliability of long span rail transit bridges, construction control is necessary. In this study, the construction control for the second longest span urban rail transit bridge is presented. First, the schemes of the bridge construction control, including the geometry control, stress control as well as cable force control of the main bridge are illustrated. Then, details for the bridge, field measurements and numerical simulation for construction control of the bridge were introduced. Finally, comparisons of the field measured construction control results and the target ones are conducted. The schemes and analyses can be referred for engineering applications and development of related specifications.
