This paper was combined with a real bridge to construct a carbon fiber arch bridge scale test model according to similar principles, thereby testing and researching on its mechanical properties. Space finite element analysis software Midas / Civil was adopted for space simulation study of all working conditions in each use stage of the model bridge. The test results showed that: CFRP hanger tension and load in all working conditions of the model experience were basically changed in a linear mode, its working conditions were normal, all working conditions were basically matched with the theoretical calculation values except the hanger whose specific anchors were provided with slight slip, which indicates that it is feasible to allocate CFRP hanger in bowstring arch bridge while indicating that calculation and analysis results of finite element program can be used to guide loading work, measuring point selection and other work of the model bridge, and the experimental data and analysis results are correct.
