| Abstract: | The design characteristics of the deck type CFST arch-bridge in Gansu Province was introduced,its main span is 180 meters, width-span ratio is 1/25.7. Using three-dimensional finite element models of the bridge, it was analysed the transverse stability of bridge during the process of construction and the final condition of the bridge, respectively. The stability of bridge under construction is the main problem of the design and construction. The indexes of the bridge during its operation meet the requirements of the highway specifications. |
| Keywords: | concrete-filled-steel tube arch rib width-span ratio stability |
