| 摘 要： | 桥梁结构静载和动载试验，可以检验桥梁的整体受力性能，评价桥梁结构的实际承载能力，是各类桥梁检测评定工作的重要手段。本文利用Nidas程序，建立了金昌某钢筋混凝土板桥有限元分析模型，模拟分析了该桥的静力特性、动力特性，将模拟结果与实测结果进行了对比分析。对比结果表明：用有限元模拟混凝土板桥的实际工作情况得出的参考数据在对桥梁实际使用过程中进行健康检测和维护中所使用是可行的，从而为桥梁的安全评定提供依据。

| Abstract: | Static load and dynamic load test of bridge structure can test the integral force properties of bridge structure,evaluate the actual carrying capacity of structure of the bridge,and is an important mean of bridge testing facilities assessment.Through a reinforced concrete girder bridge in Jinchang,the finite element software Midas is used to analyses detailed and discusses the static and dynamic characteristics of the bridge.By comparing the measured results with the simulated results,a conclusion can be dr... |
