| Abstract: | At the location where the Beijing Bridge on Beijing-Shanghai High-Speed Railway spans Beijing-Kaifeng Expressway,to meet the requirements for grade separation there and to seek for better effect of aesthetics,the type of a half-through steel box arch bridge with spans(32 108 32) m was adopted in the design,and the handling schemes for various structural parts of the bridge,such as the main girder depth,deck slab types,floor system,suspender spacing,arch rib c/c distance,suspender types,negative reaction forces on the side piers and horizontal thrust form the main piers were mainly compared and optimized. |
