| 摘 要： | 同时考虑了几何非线性和材料非线性，对浙江淳安南浦大桥进行结构非线性分析，结果表明对南浦大桥这种大跨（跨径大于300m）、宽跨比小（接近1／20）的钢管混凝土桁式拱桥，几何非线性和材料非线性的影响均较大，在设计和施工时不应忽略。

| Abstract: | Simultaneously it had considered the geometry non-linearity and the material non-linearity carry on the structure nonlinear analysis to the Zhejiang Chun'an Nanpu bridge, finally it indicated greatly cross (span is bigger than 300 m), the width steps slightly compared to (close 1/20) the steel pipe concrete clothes rack type arched bridge to Nanpu bridge this kind, the geometry non-linearity and the material non-linear influence is big, when design and construction should not be neglected. |
