| 摘 要： | 钢管混凝土拱桥可以通过改变矢跨比来改善其整体稳定性。利用有限元方法研究钢管混凝土拱桥的矢跨比对稳定性的影响,给出矢跨比的合理取值范围。结果表明,在考虑几何非线性影响的情况下,钢管混凝土拱桥的矢跨比宜选在1/3.5~1/5。 |

| Abstract: | Concrete filled steel tube arch bridge can improve the lateral stability by changing rise-span ratio. Using the finite element method, the effect of rise-span ratio on stability was studied, and reasonable rise-span ratio is given in this paper. The result shows that the rise-span ratio of concrete filled steel tube arch bridge should be about 1/3.5~1/5 when the effect of geometric nonlinearity is considered. |
| Keywords: | concrete filled steel tube arch bridge rise-span ratio stability geometric nonlinearity |
