Deformation Analysis of Railway Continuous Curved Rigid Frame Bridges in Construction Control

摘要

To study the effects of deformation on bridges, the finite element analysis method was used. The railway continuous curved rigid frame bridge has been taken into account. Both the deadweight, prestress, and creep of the concrete were used for comparative analysis about the effect on displacement and twisting angel, then some practical application conclusions were obtained. The maximum reaction values were produced in different sections under the extreme cantilever stage and the finished bridge stage. Futhermore, the study of structural spatial behaviors is of great importance.
