Abstract: The analytical method and model of structure during the construction of arch bridge with the aid of centring is studied in the paper.The feasibility of the analytical method and model and the importance of the structural analysis during the course of construction are testified by the comparison of the result from theoretical analysis,simulation test and measurement on the bridge.

Key words: arch bridge constructed by centring, construction process, structural analysis
