Research on Alignment Control of Cable-Stayed Bridge during Construction

Abstract:

Measured values of alignment deviate significantly from the predicted ones partially of a cable-stayed bridge before closure. The root-cause was analyzed and a correction program was proposed in this paper. Unreliable anchoring and instable deformation of hanging basket resulted from the difference between hanging basket structure and construction requirements are the main cause. It is difficult to adjust cable force under cantilever state and it is feasible to adjust cable force and height after the bridge is setup.
