摘　　要： 大跨度预应力混凝土连续梁桥具有结构受力性能良好、跨度大等优点,在我国公路桥梁建设中有着越来越广泛的应用。但是其在施工中往往需要转换结构体系,其力学行为较为复杂,需要在设计阶段进行详细的静力和动力分析。论文主要介绍大跨度预应力混凝土连续梁桥主桥设计分析的要点、整体静力计算分析要点和动力特性分析要点,以供参考。 The long-span prestressed concrete continuous beam bridge has the advantages of good structure and wide span, and it has been widely used in the construction of highway bridges in China. However, it is often needed to transform the structural system in its construction. Its mechanical behavior is more complicated, need to carry out the static and dynamic analysis in the design stage. This paper mainly introduces the key points of main bridge design of long span prestressed concrete continuous beam bridge, and the key points of whole static calculation and dynamic analysis, for reference.
