预应力混凝土梁拱组合体系景观桥成桥静载试验研究

Experimental Study on Static Load of Prestressed Concrete Beam-arch Composite Landscape Bridge

为评定某预应力混凝土梁拱组合体系景观桥成桥后的技术状况及承载能力,采用桥梁分析软件MIDAS/FEA进行计算,并对该桥进行静载试验,根据静载试验的试验结果与数值模拟值比较研究。研究结果表明:测试跨桥梁结构强度、刚度以及抗裂性能均符合有关规范要求,桥梁结构处于弹性工作状态,该桥结构技术状况及承载能力满足设计荷载标准的正常使用要求。

In order to evaluate the technical status and bearing capacity of a prestressed concrete beam-arch system landscape bridge after it is completed,the bridge analysis software MIDAS/FEA is used for calculation,and the bridge is subjected to a static load test.The test results of static load test are compared with the simulated calculation values.The research results show that the strength,stiffness and crack resistance of the spanned bridge structure meet the requirements of the relevant specifications.The bridge structure is in an elastic working state.The technical status and bearing capacity of the bridge structure meet the normal use requirements of the design load standard.
