摘　　要：斜拉桥索梁锚固区结构复杂,受力集中,是控制设计的关键部位。针对高家花园轨道专用桥钢箱梁段索梁锚固区,利用ABAQUS通用有限元软件建立三维有限元模型,并采用线弹性模型及理想弹塑性模型对不同索力作用下的钢箱梁锚固节段进行计算和分析。计算和分析表明,钢锚箱结构受力合理。此外,还对索梁锚固区受力规律进行分析,为进一步优化设计提出依据。The cable-beam anchorage zone of cable-stayed bridge has complex structure and concentrated force,which is the key part of control design. 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.
