预应力钢筋混凝土连续箱梁桥的各种设计方法的研究

Study on Design Methods of Prestressed Reinforced Concrete Continuous Box Beam Bridge

列出了三种预应力钢筋混凝土连续箱梁桥的施工方法,应用有限元软件从力学特性上进行了分析,并对施工工期、施工难度、施工灵活性四个方面进行了分析比较。最后推荐出适合城市立交设计施工的方法。

The construction methods of three prestressed reinforced concrete continuous beam bridge are listed by finite element software from the mechanical characteristic and the four aspects of construction methods,construction period,construction difficulty and construction flexibility are analyzed and compared.The methods on city interchange design and construction are recommended.
