摘要
介绍泰州某独塔斜拉桥成桥荷载试验的主要内容和方法,并结合有限元数值计算,对该桥梁结构的实测应力、挠度及振动特性进行对比分析。试验结果表明:该桥理论分析和设计计算方法可靠,桥梁刚度和承载能力满足设计要求。研究结果可为同类型桥梁的设计和成桥试验提供参考。
The principal contents and methods of load tests for Taizhou Single-pylon Cable-stayed Bridge at completion stage are presented. In compliance with the finite element numerical calculation concerned, the stress, deflection and vibration behavior of the bridge structure measured in the tests are compared and analyzed. The results of the tests show that the theoretic analysis, design and calculation methods for the bridge are reliable, and both the structural rigidity and carrying capacity thereof can satisfy the design requirements. The results of the study may provide reference for the design and for tests at completion stage of similar bridges.
