摘　　要：本文采用ANSYS11.0和MIDAS/Civil,对一下承式单索面钢箱叠合梁钢管混凝土系杆拱桥的吊杆锚箱以及混凝土桥面板进行了局部分析,重点关心吊杆锚箱以及混凝土桥面板在两种工况下的应力大小和分布情况。通过计算分析,给出了吊杆锚箱的最大Mises应力和混凝土桥面板拉应力的范围和大小,结构设计满足规范要求,同时为类似结构的设计与施工提供参考。In this paper, based on finite element software ANSYS11.0 and MIDAS/Civil, suspender anchor box and concrete bridge deck of a single cable plane steel box composite beam CFST tied arch bridge with suspended road were analyzed. The stress and distribution of the suspender anchor box and concrete bridge deck under two load cases were mainly considered. By calculation and analysis, maximum Mises stress of the suspender anchor box and the tensile area and the tensile stress of the concrete bridge deck were listed. The results showed that the design could meet the specification requirements, and could provide a reference for the design and construction of similar structure.
