| Abstract: | The main bridge of Fumin Bridge in Tianjin is a single tower and spatial cable plane self-anchored suspension bridge.The main cables of the bridge over the main span are of the three-dimensional curved geometric shape,the hanger cables thereof are the inclined ones in the bridge transverse direction and the initial tensile force of the main cables has substantial influence on the construction schemes for the spatial cable system of the bridge.This paper mainly makes a study of the influence of the initial t... |
