| Abstract: | With the help of finite element software,this paper establishes a three-dimensional simulation model of some continuous rigid structure curved bridge,generalizes the influences of central angles on static characteristics of large-span continuous rigid structure curved bridge by comparing the force and deformation of structure caused by central angles of different curves,and proposes corresponding recommendations for design and calculation of large-span continuous steel structure curved bridge. |

| Keywords: | continuous rigid structure curved bridge bending coupling radius of curvature central angle |
