| 摘 要： | 淳安南浦大桥为一净跨径308m中承式钢管混凝土桁式拱桥，宽跨比较小，该桥拱肋的横向稳定是桥梁安全性的关键，文章运用非线性稳定分析的基本理论，得出了该桥在不同风荷载作用下稳定性分析的结果。结果表明：风荷载对该桥稳定性的影响很小，而材料非线性对该桥的稳定性影响较大。

| Abstract: | Chunan Nanpu Bridge is a half-tied concrete filled steel-tube arch bridge. The span is 308 m and the rate of width to span is much smaller. The stability of arc ribs is the key of bridge safety. By applying the basic theory of nonlinear stability analysis, the author obtains the result of stability under different wind load. The result shows that wind load has little influence on the stability of the bridge, while the material nonlinear is on the opposite. |
