So far, as one of the ancient bridge type, the development of Arch Bridge has had a long history about tree thousand years. Compared to the long history of Arch Bridge, the history of CFST was just hundred years, but it developed so fast. In the area of arch, the superior of its span ability of CFST has obtain majority of bridge engineers favorite, especially that some bridges should be span on the deep groove or canyon. Even though during setup the CFST arch ribs, used to pouring concrete after setup the arch ribs, due to the light weight of structure, that make spanning and constructing more convenient, but the history to short for this construction of bridge, so there is still not perfect for the design theory and design specifications. From the development of today, the span debility of CFST arch bridges was growing, it has demand up for the Construction Control.The Hanyang River of this article discussion was belong to CFST Arch bridge on duck, using erection with cable way during the construction process, because of the capacity of cable hoisting was limited, so the arch ribs were assembling segmental. So there comes a very profound questions to the construction control, that is how to control the linear of Arch Axis, so that it can meet the design expectations of state. The achievement of construction control in Hanyang River Bridge we discussed in this paper, we will research and Discussion on this issue.At first, briefly expounds the origin, characteristics and development process of the CFST arch bridge, and brief introduction the construction control theory and method of the CFST arch bridge, to clarify the purpose, significance and contents of arch bridge construction control. Due to this, let's have a shallow understanding of the construction of arch bridge, such as the analysis method of construction control, and how to calculate an analysis of arch rib.The second, we use Midas/Civil, one of the finite element calculation software to simulation the construction process of Hanyang River bridge, draw the deformation in different situation of arch rib, to provide reference for the setting of elevation control during the construction process. During the creation process, we make simulation calculation analysis and real-time tracking analysis for the arch rib, ensure that the linear of design can meet the linear of actual. Analyze the linear change as factors causing of the arch rib hoisting process, the pre-elevation of arch rib calculated through theoretical, can be optimize the construction.
