Take a typical continuous rigid-frame bridge as the background, and through the selection of curvature radius and pier height, this paper takes the influences of stage structure self-gravity of cantilever construction and suspended casting prestress into consideration, and analyses the stress and deformation of curved continuous rigid-frame bridge in the biggest cantilever construction stage with finite element program, pays much attention to the research of the influences of curvature and pier high. Through the analysis, the author provides the corresponding design suggestions and construction control ideas for the curved rigid-frame bridge.
