| Abstract: | The rib hoisting of large-span steel pipe concrete arch bridge is a complex course. In order to ensure that the final bridge line and the forced status meet the design requirement, it needs to adopt the calculation of the construction control imitation. The paper gives the actual steps of imitative calculation and puts forward the advancing analysis method based on iterative theory and verifies the feasibility of this method through the example. |
