Analysis of Parameters Influence on Structure of Continuous Curved Bridge

摘要

In the modern urban bridge projects, especially the urban interchange projects and the urban viaduct projects, the long-span curved bridge with the small radius is often inevitably used, considering the transportation under bridges, pipelines and aesthetic factors. This kind of long-span curved bridge with small radius was adopted on the south of Second Ring Road in Chendu of the project of "Two Expressways, Two Extended Roads, Two Ring Roads". The influence, which the change of the parameters on the structure had, was analyzed by using the finite element software of Midas Civil 2010. Then, the parameter which had greatest impact on the inner force of the structure was found. The girder depth is the key parameter in design.
