In view of the greater difficulty in the process of curved continuous rigid frame bridge construction, as well as the greater complexity of the stress and deformation in the construction process than that of the linear bridge, a bridge model has thus been established by using the finite element software Midas/civil based on a case study of the landscape bridge of Tongxi Road, followed by a study on the deformation difference at different construction stages, to be compared with the measured data to verify the validity of the model. The results show that the vertical displacement of the box girder increases with the increase of the cantilever length in the symmetrical construction process of the bridge, and the vertical deformation of the side span box girder is different from that of the middle span box girder, with the deformation of the side span box girder greater than that of the middle span box girder; while in the asymmetric construction process, the self weight of the concrete has a greater impact on the deformation of the bridge structure, which will cause the box girder up deflection near the middle of the side span, with the maximum deflection reaching as high as 10 mm. After the completion of the bridge, the concrete shrinkage and creep have a great impact on the bridge structure alignment, mainly located near the middle of the mid span; meanwhile the curve radius has a certain influence on the deformation of the bridge structure, with the vertical deformation and transverse deformation of the curved continuous rigid frame bridge decreasing with the increase of the curve radius.
