摘要
变截面连续箱梁是当前大跨径梁桥中最常用的结构形式,为研究其在荷载作用下的动力性能,以嘉兴秀虹大桥为研究对象,通过有限元软件Midas建模分析和现场荷载试验对比分析,研究了典型结构的变截面连续箱梁的动力性能。通过对比得出,秀虹大桥的实际荷载试验结果与理论基本一致,且桥梁结构刚度和强度满足设计要求,并在弹性工作状态。该研究对类似桥梁的研究和设计提供了较好的参考依据。
Variable section continuous box girder is the most common structural form of long-span girder bridges.In order to study the dynamic performance of load testing,the paper takes the Xiuhong bridge in Jiaxing as the research object.Through comparison between Midas modeling analysis and field load testing,the paper studies the dynamic performance of the typical variable crosssectional continuous box girder.Through the comparison,the actual load test results of Xiuhong bridge are basically consistent with the theory,and the structural rigidity and strength of the bridge meet the design requirements,and the bridge is in elastic working state.The study provides a good reference for the research and design of similar bridges.
