| 摘 要： | 平胜大桥是一座独塔自锚式混合型悬索桥。为了了解其整体受力特性，利用有限元软件，建立了该桥的力学模型，对主梁和主塔采用梁单元离散，主缆和吊杆采用桁架单元离散，计算了四种工况下主梁、主塔和主缆、吊杆的内力及位移，整体上分析了该桥的力学特性。结果表明，该桥应力和位移均满足规范要求，是安全可靠的。

| Abstract: | Pingsheng Bridge is a self-anchored and mixed suspension bridge. For understanding the mechanical behaviors of the bridge, its mechanical model is set up by means of finite element software. The main beam and main tower are dispersed with beam elements, and the main cable and suspend bar are dispersed with truss elements. The internal forces and displacements of the main beam, main tower, main cable and the suspend bar in the four kinds of working conditions are calculated. The mechanical behaviors of the bridge are analyzed in whole. It is showed from the computed results that the internal forces and displacements could meet the requirements of standard, and the bridge is safe and reliable. |
