| 摘 要： | 采用有限元法对大跨度中承式肋拱桥进行动力特性分析,为该类桥型设计及健康监测、状态评估提供有用数据。通过动载试验,检验桥跨结构的实际承载能力、结构变形及动力性能是否满足设计要求,寻求桥梁整体结构的变形规律,了解结构的实际受力状况和工作状况,为日后运营、养护及管理提供科学依据;建立与该类桥梁有关的技术档案,为今后兴建同类桥梁完善设计、优化结构、改进工艺积累实测资料。

| Abstract: | The dynamic characteristics of long-span semi-supported arch bridges are analyzed by the method of finite element aiming to provide useful data for bridge design, healthy inspection and condition estimation. The move-loading tests can tell whether the actual loading ability, the structural change and the dynamic characteristic of a bridge meet the design demand, and the changing regularity of the whole structure of the bridge and the actual loading condition as well as the working condition can be known, which can offer scientific bases for bridge utilization, conservation and management in the future. Then the technical files for the same kind of bridges can be set up, by which actual data in improving design, optimizing structure, and improving technics can be accumulated. |
