| 摘 要： | 文章以绩黄高速公路某大桥为例，分析了几何非线性和材料非线性等因素对大跨度钢管混凝土桁式拱桥结构非线性的影响，结果表明对跨径大于300m、宽跨比接近1／20的钢管混凝土桁式拱桥，几何非线性和材抖非线性的影响均较大，在设计和施工时应注意，供同行参考。

| Abstract: | With a bridge from the Ji-Huang expressway as an example, this paper analysed the nonlinear effect of geometric nonlinearity and material nonlinearity on big-span steel-pipe concrete trussed arch bridge structure, indicating that both geometric and material nonlinearity show a bigger effect for a bridge with a span over 300m and width/span ratio up to 1/20, and should be taken into consideration in design and construction. |
