In this paper, for the bridge girder anchorage zone of Gaojiahuayuan Track Bridge, 3D finite element model is established by using ABAQUS general finite element software. And the linear elastic model and the ideal elastic-plastic model are used to calculate and analyze the anchorage section of steel box girder under different cable forces. The calculation and analysis show that the steel anchored box structure is reasonable in the force. In addition, analysis carried out for force rules of the cable-girder anchorage zone, so to provide reference for further optimization design.
