| Abstract: | Continuous rigid frame bridge with box section is one of the most popular structure types in the bridge construction in China.Big widespread deformationin often appears in midspan of the brigdes.Factors affecting deformation of the midspan of continues rigid frame bridge are plentiful and complex.The key factors affecting continuous rigid frame bridge midspan deformation were analyzed and summarized.By the basis of a continuous rigid frame structure—Baiguodu Bridge,various parameter affecting continues rigid frame bridge deformation were analyzed.The prevention and cure measures on this foundation are put forward. |
