空间蝶形拱桥静动载试验研究

Static and Dynamic Load Test Research of Spatial Butterfly Arch Bridge

以某市政人车分离设置的空间蝶形拱桥静动载试验为例,从有限元建模模拟、加载工况、测点布置、结果对比等方面,介绍了此类桥梁荷载试验方法,试验测试结果良好,桥梁测试变化规律和理论分析结果完全符合,可为相关桥梁检测提供参考。

Taking the static and dynamic load test of a spatial butterfly arch bridge with the municipal man-vehicle separation as the example,the load test methods of this kind of bridge are introduced from the aspects of finite element modeling simulation,loading conditions,measurement point arrangement,and result comparison and so on.The test results are good,and the change law of bridge test and theoretical analysis results are fully consistent,which can provide reference for relevant bridge detection.
