摘要
用小直径钢管混凝土劲性骨架修建大跨度拱桥,可以减轻转动体系重量,降低转体桥造价。本 文介绍了它的材料特性、转动体系构造和施工要点。
The minor-diameter steel-tube concrete rigid skeleton used in the construction of large-span arch bridge can reduce the weight of swivel system and minimize the cost of swivel body. The material feature, structural and construction essentials of the swivel system are introduced in the paper.
