摘要
以一座已加固的钢筋混凝土双曲拱桥为工程背景,建立空间有限元分析模型,计算该桥的内力、变形和自振特性。通过荷载试验,比较分析加固前、后的计算结果和试验结果,对加固后的桥梁承载能力进行评定,为该类桥梁的维护使用和加固改造工作提供可靠的技术支持。
By taking a strengthened concrete double curved bridge as studying object,its space finite element model was built.The deformation,stress and self-vibration of the bridge were calculated and their charactertstics were analyzed by the model.Compared the calculation results and the load test results,the load bearing capacity of the reinforced bridge was evaluated.The studying results can provide a reliable technical suport for maintenance and reinforcement of this kind of bridge.
