Design of Rotating Cable-stayed Bridge of Yangsigang Expressway of Wuhan City
摘要
Abstract
The rotating cable-stayed bridge of Yangsigang Expressway of Wuhan is China's first semi-floating structural system cable-stayed bridge with single-column pylon. The span arrangement is (40+88+252+88+40) m. The main bridge is designed in bi-direction with eight lanes and the sidewalks are set on both sides. The weight of rotation is about 17 500 t and the rotating radius of the bridge is 124 m. The main girder is of whole steel box girder with central double cable planes,the pylon of the bridge is single-column reinforced concrete structure and the high strength parallel steel wires are used in the stay cables. This paper expounds the design features of the bridge,the location of the main bridge, the selection of the bridge scheme,the structural structure and conducts calculation and analysis. The static calculation,rotating structural calculation,seismic analysis and stability analysis of the main bridge are carried out by using finite element software. The calculation results show that the components of the bridge are safe and reliable with good bearing capacity and the bridge has good static and dynamic performances. The wide steel box girder cable-stayed bridge with single-column pylon and central double cable planes is proved economic and aesthetic and it can provide reference for the design of overpass railway bridge and further promotion.关键词
