摘要: 以重庆市江津区滨州路一号桥为研究对象,采用大型通用有限元软件ANSYS,分别建立了4 种不同构造形式 的吊杆锚固结构模型,进行计算分析。结果表明: 吊杆与拱肋中心线夹角的变化对锚固结构的极限承载力、刚度变 化影响微小,而圆管与拱肋底板连接形式对其影响较大。

关键词: 下承式拱桥, 钢箱拱肋, 吊杆锚固结构, 受力分析

Abstract: Binzhou Road NO. 1 bridge in Jiangjin of Chongqing was taken as the research object. Four suspender anchor structure models of different tectonic forms were established and calculated by using large common software ANSYS. The analysis results show that the changes of the angle of the suspender and arch ribs centerline would affect limit ultimate bearing capacity and stiffness variation slightly while the connection form of pipe and arch ribs bottom would affect them largely.

Key words: through arch bridge, steel box-girder arch rib, suspender anchor structure, stress analysis
