摘要
钢混组合索塔斜拉桥在景观桥梁及大跨度桥梁中运用非常广泛,而钢混结合段作为索塔传力的核心构件,其结构设计及连接方式对全桥结构安全极为重要。在总结前人研究成果的基础上,以府保黄河三桥为例,针对景观斜拉桥钢混组合索塔的构造及性能进行分析,为今后类似桥梁设计提供有益参考。
The steel-concrete composite cable-stayed bridge is widely used in landscape bridges&long-span bridges,and the steelconcrete composite section,as the core component of the cable tower force transmission,its structural design&connection mode are very important for the structural safety of the whole bridge.On the basis of summarizing the previous research results,taking the Third Bridge of Fubao Yellow River as an example,this paper analyzes the structure&performance of the steel-concrete composite pylon of the landscape cable-stayed bridge,which provides a useful reference for the design of similar bridges in the future.
