摘要
异型拱桥是一种较为新型的、特点鲜明的空间组合结构体系桥梁建筑结构,由普通拱桥演变发展而来,外形美观、造型新颖。四新南路跨总港桥采用一跨异型拱桥,计算跨径56 m,采用两榀反对称钢箱主拱圈,无风撑连接,主梁采用预应力混凝土结构。阐述该异型拱桥的结构设计与计算分析。
The special-shape arch bridge is a more new and distinctive spatial composite structure system bridge structure and is developed from the normal arch bridge with the novel appearance and innovative design. The South Sixin Road Bridge crossing Zonggang is a one-span special-shape arch bridge. The calculated span is 56 m. The double-pin antisymmetric steel box arch ring is used without wind bracing. The main beam is the pre-stressed concrete structure. The article sets forth the structural design and calculation analysis of this special-shape arch bridge.
