摘　　要：在油气长输管道建设和水利工程中经常采用跨越管桥结构。以渭惠渠跨越段工程中某悬索跨越管桥结构为实例,利用有限元软件ANSYS建立悬索跨越管桥结构三维有限元分析模型,通过三种工况下的静力性能分析,获得节点的位移及单元的最大应力值,结果表明该悬索跨越管桥结构在静力作用下是安全的。通过动力特性分析得到悬索跨越管桥结构的各阶自振频率和振型,有利于同类结构的设计。The spanning pipe bridge structure is often used in the construction of long-distance oil and gas pipelines and water conservancy projects.Taking a suspension cable spanning pipeline engineering structure as an example,the 3D finite element model of the suspension cable spanning pipeline structure is established by finite element software ANSYS.Static performance analysis under three working conditions is made,and the displacement of the node and the maximum stress value of the element are obtained.The results show that,the suspension cable spanning pipeline structure is safe under static action.The natural frequencies and modes of the suspension cable spanning pipeline structure are obtained by dynamic analysis,it provides reference for seismic design of similar structures.
