梁拱组合桥柔性吊杆张拉力的确定及分析

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。

Determination and Analysis of Tensile Force of Flexible Hanger Rods for Beam-Arch Combination Bridge

The paper analyzes and studies on the internal force of the flexible hangcr rods of beamarch combination bridgc under the status of the completed bridge. The internal force of the hanger rods when completing the bridge shall be determined by displacement,bending movement and the integral forced status as the control objective. At thc same timc,the internal force of the hanger rods determined by these methods shall be compared to select a reasonable method for the reference of the spreading and application of the future same kind of bridges in design and construction analysis etc.
