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 theoret...
