Abstract: A spatial nonlinear model is established and the linear and nonlinear analyses of stability on a large-span CFST arch bridge are maken during its construction process and the serving phase through the Nastran structure analysis system. Discussions on various kinds offactors which would afect the stability of a CFST arch bridge are made.As a result.some important conclusions arc obtained ,which may be valuable for the design and construction of such kind of bridge.

Key words: CFST, nonlinear, stability
