双塔斜拉与连续刚构组合桥荷载试验研究

Study on Load Experiment of Double-pylon Stayed Cable and Continuous Rigid Frame Composite Bridge

结合工程介绍了某双塔斜拉与连续刚构组合桥荷载试验内容和方法。通过建立该桥有限元模型,测试了结构在试验荷载作用下的应力、挠度、塔偏、梁端转角、索力增量及动力特性,并分析了该桥强度、刚度和动力性能。其成果可为同类型桥梁设计和试验提供参考。

Combined with the projects, the article introduces the load experiment contents and method of a double-pylon stayed cable and continuous rigid frame composite bridge. The finite element model of this bridge is established to test the stress, deflection, pylon deviation, beam end corner, cable force increment and dynamic characteristic of structure under the test load, and to analyze the strength, rigidity and dynamic performance of this bridge, which can be referred for the design and experiment of the similar bridges.
