摘要
简要对预应力混凝土连续刚构桥桥型和结构尺寸的选择、设计以及结构受力分析进行了介绍.大桥采用主跨为85 m的预应力混凝土连续刚构桥,主梁采用单箱单室变截面箱型梁,配置三项预应力体系,下部结构采用矩形薄壁空心墩,钻孔桩基础.通过对该桥进行结构分析,桥梁各部分均满足规范要求,具有较好的安全性能.总结该桥的设计要点,为其他同类桥梁设计提供参考.
This paper briefly introduces the choice and design and force analysis of bridge type＆structure size for the prestressed concrete continuous rigid frame bridge. This bridge has adopted the prestressed concrete continuous rigid frame bridge with main span of 85 m. A variable section box girder with single box and single chamber was adopted for the main girder of the main bridge with three - way prestresssing system, rectangular thin - walled hollow pier and bored pile foundation was adopted for substructure of the bridge. Each parts of this bridge meet standard re- quirements by analysing structure for the bridge, and the safety properties are better of this bridge. This paper sum- marizes main points of this bridge design for giving some reference to related technical personnel.
