斜拉桥静动力性能测试研究

Study on Static and Dynamic Performance Test of Cable Stayed Bridge

静动载试验系对成桥后的桥梁承载能力与性能进行鉴定最为直接的方法之一,但试验中的具体方法、控制参数等均应因桥而异。文章以一座单塔单索面竖琴式预应力混凝土桥为例,详述了静动载试验的原理、方法、过程、测试项目、试验工况等。试验结果表明:采用该方法对该类型桥梁进行静动载试验是合理可行的。结论中亦提出大桥使用中应注意的事项,为大桥营运提供了科学依据。

Static and moving load experiment is one of the most direct methods to identify the load bearing capacity and performance of bridge, and detailed methods and control parameters are different for different bridges. Taking the single pylon single cable plane prestressed concrete cable-stayed bridge as example, the paper discusses the principle, methods, testing items, and experiment conditions, etc.The result of experiment shows that it is feasible to do static and moving load experiment in this type bridge, and proposes points merit attention while applying the method th great bridge.
