摘要
大芦线二期浦星公路主桥采用计算跨径230 m的下承式系杆拱桥,主拱为提篮式钢箱结构,主梁为钢-混凝土组合梁。介绍了该桥的工程概况、主要技术标准、建设条件及总体方案,对主梁、主拱、吊杆等主桥结构设计进行了详细的论述,并进行了主要构件的静力计算及主桥整体稳定分析。
The main bridge of Dalu Line Phase Ⅱ Puxing Highway is a 230-m span through bowstring arch bridge. The main arch is the basket-type steel box structure. The main girder is the steel-concrete composite girder. The article introduces the engineering situation, main technical standards, construction conditions and overall scheme of this bridge, discusses the main structural design of main girder, main arch and suspender in detail, and analyzes the static calculation of main components and the integral stability of the main bridge.
