为了进一步研究不同施工顺序对钢筋混凝土拱桥受力性能的影响,参照某钢筋混凝土拱桥,通过建立有限元计算模型,分析了两种不同施工顺序下主拱圈及侧墙板的受力情况,得到了不同的施工顺序对改善拱圈受力状态效果不明显、对改善侧墙受力状态效果显著的结论。此外本文还分析了整体升降温对钢筋混凝土拱桥施工力学性能的影响,计算结果显示,温度对钢筋混凝土拱桥受力影响显著。
In order to study the influence of different construction order by behavior of reinforced concrete arch bridge,with reference to a reinforced concrete arch bridge,through the establishment of finite element model to analyze the forces at two different construction order,the main arch and side wall panels,analysis was different construction order to improve the stress state of arch effect is not obvious,different construction order to improve the sidewall stress state effect is remarkable.The paper has analyzed the impact of the overall heating and cooling on the mechanical behavior of reinforced concrete arch bridge construction,calculations show temperature on the reinforced concrete arch bridge significant force.
