# 异形独塔斜拉桥张拉顺序研究Study on Tensioning Sequence of Cable for Abnormal Single Pylon Cable Stayed Bridge

Abstract: The tension sequence problem of the abnormal cable stayed bridge is very complicated. As cable stayed bridges are highly statically redundant structures, the structure systems are constantly changing with the construction process and the tension of the cable will affect the stress state of the structure. And it is important to determine the tension time of the back cable in the cable stayed bridge. In this paper, we make a construction stages analysis of different tension schemes, and compare various solutions by the parameters of the stress state of the bridge, like the stress of the cable, main girder and the main tower stress and deformation and so on. At last, we get the optimal cable tension schemes, which will provide guidance for the construction process and be time saving.
