| 摘 要： | 对一座540m自锚式钢管混凝土拱桥，进行了空间有限元模拟分析，应用大型通用有限元程序对大桥建立了模型，解决了桥梁细部诸如支座、刚臂等细节的处理；最后对大桥的有限元模型进行了动力特性计算，得到了振型、频率的数据，可以对大桥的动力性能做出评价，有助于今后建立大桥的档案和健康诊断评估。

Analysis of Power Property of Self-anchored Concrete Arch Bridge Steel Piped |

| Abstract: | For a self-anchored concrete arch bridge steel piped of 540m the anolog analysis of space finite element has been made. Utilization of large-seal finite element program in common use has established model for bridge, solving the treatments for bridge details as sustainer, rigid ann etc. Finally,the power property counting has been performed for finite element model of bridge, achieving the data as vibration type and vibration frequency. Like this, assessment of power proerty of bridge would be finished, which make contribution to establishment of files for bridge and diagnosis of bridge health. |
