The transverse width of such box girder bridge is larger, the span width ratio increases, the force of the bridge is more complex, and the effect of constraint torsion and deformation is more obvious. In order to study the stress distribution of wide continuous beam bridge cross section under different load conditions, using the combined finite element method to establish various load conditions of transverse annular frame calculation model, for a city rail transit engineering single box of multi-chamber prestressed concrete box girder bridge under the action of live load. The structural reinforcement was optimized based on the finite element calculations. In the construction of bridge, the transverse force of box girder should be considered to ensure the safety of bridge structure design.展开更多
