Static Analysis of Special-shaped Prestressed Continuous Box Girder Structure in Urban Interchange

摘要：

　　With the development of urban overpass,its very important in practical to carry out the 3D mechanic analysis on non-uniform box girder structure in the intersection between main line and ramp in the same driving direction.Based on the structure and stress characteristics of one special-shapes prestressed concrete continuous box girder bridge in China,the paper summarizes the common analysis methods in this type of structure.Based on the grillage theory,the finite element model of the structure is built with bridge analysis software Midas Civil,so as to obtain the mechanic result of the bridge,and some useful conclusions is drawn.
