摘要
对梁拱组合桥柔性吊杆在成桥状态下的内力进行分析研究。分别以位移、弯矩及整体受力状态为控制目标来确定成桥时吊杆内力。同时对这几种方法所确定的吊杆内力进行比较 ,选择一种合理的方法 ,为今后同类桥梁的推广应用提供设计、施工分析等方面的参考。
The paper studied and analyzed internal force of flexible steeve of combinatorial bridge beam and arch under the state of the bridge completed,and confirm internal force of flexible steeve after the bridge completed taking Displacement,moment of flexion and holistic atress as control object,while internal force of flexible steeve confirmed by the methods were compared,and choose a reasonable method for application of the same bridges,for reference in design and construction later.
