| Abstract: | This paper introduced the main construction methods of large span CFST arch bridge, and taking a deck type CFST arch bridge for example, used the large finite element analysis software MIDAS made numerical simulation to this kind arch bridge. Analysed the internal force and deformation in upper structure installation each stages of large span CFST arch bridge, provided some guidance for the eonstruction control of similar large spanCFST arch bridge. |
