预应力混凝土简支T梁桥荷载试验

Research on Load Test of Prestressed Concrete Simply Supported T-beam Bridge

结合某预应力混凝土T梁桥,介绍了静力荷载试验的内容与方法,包括测点布置、荷载布置、加载方式以及试验结果与计算结果的对比分析等。通过静力荷载试验与有限元软件相结合的手段,测试桥跨结构强度、刚度,检验桥跨结构在正常使用状态下承载能力和结构变形是否符合设计要求。结果表明,该桥结构处于正常受力状态,结构刚度、强度均满足规范要求。

Combined with a prestressed concrete T-beam bridge,this paper introduces the contents and methods of static load test of the bridge,including the arrangement of measuring points,load arrangement,loading mode,and the comparative analysis of test results and calculation results.Through the combination of static load test and finite element software,the strength and stiffness of the bridge span structure are tested to check whether the bearing capacity and structural deformation of the bridge span structure in normal condition meet the design requirements.The test results show that the bridge structure is in normal stress state,and the structural stiffness and strength meet the specification requirements.
