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 internal force analysis of the flexible arch bridge with beam-arch composite bridge under the bridge condition is carried out. Respectively to displacement, bending moment and the overall state of force as the control target to determine the bridge when the boom force. At the same time, the author compares the internal forces of the boom determined by these several methods and chooses a reasonable method to provide reference for the design and construction analysis of similar bridges in the future.
