空腹式钢筋混凝土板拱桥设计及分析

Design and Analysis of Hollow Reinforced Concrete Slab Arch Bridge

拱桥作为一种历史悠久的桥梁结构体系,在20世纪有了较长足的发展。近年来随着桥梁施工技术的不断提高,拱桥的设计往往更倾向于现代化的大跨度钢管混凝土组合体系。但是钢筋混凝土拱桥有着造型美观、耐久性好、养护费用低等优点,仍被广泛应用于一些中小跨度桥梁建设中。通过实际工程设计案例,对空腹式钢筋混凝土板拱桥的计算理论,模型的简化及计算结果进行研究分析,并提出对工程设计实质性的建设性意见。

The arch bridge is a bridge structure system with a long history, and was considerably developed in the 20 th century. In recent years, the design of arch bridge even more tends to the modern long-span concrete filled steel tube composite system. But the reinforced concrete arch bridge has the advantages of beautiful modeling, good durability and low maintenance cost, and is still widely used in some constructions of small-span and middle-span bridges. The article studies and analyzes the calculation theory, model simplification and calculation result of hollow reinforced concrete slab arch bridge through the practical engineering design cases, and puts forward the constructive proposal for the engineering design.
