| Abstract: | Because of the mechanic feature of large span continuous rigid frame bridge with wide box girder itself,the phenomena of cracks of the box girder and excessive deflection in the middle of the span widely exist.Taking Nanhedi Bridge as an example,both global and partial analysis on this bridge is carried out,using 3D finite element method.The problem how to avoid the cracks in the box girder and excessive deflection in the middle of the span is resolved through the analysis and comparison which is worthy to ... |
