摘要
文章对佛山某变截面钢箱梁桥主桥进行荷载试验,并借助Midas Civil软件建立有限元模型模型进行对比分析,采集在不同加载工况下的荷载数据,最后对比试验实际值和理论值,试验证明该桥满足公路-Ⅰ级设计等级的要求,通过试验对桥梁结构的实际工作状态、结构的整体承载性能,为类似交工检测中新建桥梁承载能力评定提供参考依据。
In this paper,the load test is carried out on a main bridge of a variable cross-section steel box girder bridge in Foshan,and the finite element model is established by Midas Civil software for comparative analysis.The load data under different loading conditions are collected,and the actual value and theoretical value of the test are compared in the end.The test proves that the bridge meets the requirements of highway-I design level.The actual working state of the bridge structure and the overall bearing capacity of the structure are tested through the test,which provide references for the evaluation of the bearing capacity of the newly-built bridges in similar delivery inspection.
