| 摘 要： | 以某主跨为152 m的钢管混凝土箱形拱桥为例,用有限元方法建立其空间计算模型,分析矢跨比等设计参数对拱圈截面内力的影响,并在考虑混凝土收缩徐变的情况下,分析各控制截面内力和位移随时间的变化关系.表明:拱桥矢跨比对其轴力和弯矩影响较大;随着时间的推移,拱桥结构内力和位移有很大改变. |
| 关 键 词： | 拱桥 钢管混凝土结构 矢跨比 徐变 |

| Abstract: | A bridge is a concrete filled steel tube box arch bridge,whose span is 152 m.Establishing a spatial model with finite element method and analyzing the effect of design parameter such as height span ratio to the structural internal force are carried out.Considering the shrinkage creep,the relationship of interface forces and displacements with time are derived.The results indicate that height span ratio affects the axial force and the moment of arch bridge greatly,and the internal force and displacement of arch bridge changed substantially with the passage of time.This conclusion has an important meaning for the bridge design and computation of other arch bridges. |
| Keywords: | arch bridge concrete filled steel tube height span ratio creep |
