摘要
基于国内某悬索斜拉索组合式跨越管桥现状,应用有限元分析技术软件,通过选用合理的有限单元以及对有限元模型输入参数的修正,根据20年前建造时成桥状态和服役20年后管桥状态的变形测量结果,建立了管桥有限元计算模型。通过静力计算,得到管桥在输油状况下的位移和应力,为管桥安全评价提供了依据。
Based on the deformation measurement of the state of the pipeline bridge at construction and after serviced 20 years,a finite element model for analyzing the suspension and cable-stayed combined pipeline bridge is set up by using the finite element analysis software and choosing the right finite elements and by the modification of the input parameters. The displacements and the stresses of the bridge under the state of oil transportation are obtained by static analysis, and provide a basis for the safety assessment of the pipeline bridge.
