摘要
钢筋混凝土弯箱梁桥因其良好的力学性能及经济性,同时对道路线型的适应性,在城镇立交设计及公路路网交叉节点设计时得到了广泛的应用。现分析弯箱梁桥的力学性能及受力特点,并结合工程实例探讨有关弯箱梁桥支座布置及抗倾覆的问题,总结出弯箱梁桥在设计过程中的注意事项及解决方法,为同类桥型的设计提供一定的参考。
The steel reinforced concrete bent box beam bridge is widely used in the design of town grade separation and the highway network cross point because of its good mechanical property and economy,and also its adaptability for road alignment.The article analyzes the mechanical property and stress characteristics of bent box beam bridge,and according to the engineering cases,discusses the support layout and anti-capsizing problem of bent box beam bridge,and summarizes the attentions and solving methods in the design of bent box beam bridge,which can be referred for the design of the similar bridges.
