| Abstract: | The designed span length of Lingyun bridge in Dangtu is 29.4 m＋80.5 m＋93 m＋80.5 m＋29.4m,the middle three spans are concrete-filled steel tubular tied-arch bridge and the two ends are reinforced concrete deck arch bridge （half arch）. This paper introduced the static calculation and stability analysis of different hoisting sequence of crossbeam and verified the feasibility of the selected proposal. |
