跨黄河特大桥之悬索桥与斜拉桥技术经济对比分析

特大桥梁作为跨越大江大河的主要交通形式,越来越多地出现在黄河之上,而悬索桥与斜拉桥最为常见。结合工程实例——山东省济南市凤凰路北延跨黄河特大桥,通过不同桥型的比较,分析悬索桥与斜拉桥在技术经济上的各自特点及差异,应根据不同情况综合比选桥型方案,选取最合适的桥型。可为今后同类工程的方案选择及造价编制提供参考。

Comparison and Analysis on Technologies and Economies of Suspension Bridge and Cable-stayed Bridge Spanning Yellow River

As the main traffic mode spanning the big rivers,there are more and more extra-long bridges on the Yellow River.The suspension bridge and cable-stayed bridge are the most common.Combined with an engineering example-Fenghuang Road North Extension Bridge spanning the Yellow River in Jinan City of Shandong Province,after the comparison of the different bridges,the characteristics and differences of suspension bridge and cable-stayed bridge are analyzed in the technologies and economies.According to the different circumstances of the comprehensive choice of bridge schemes,the most suitable bridge type is selected.The reference can be provided for the scheme selection and the cost preparation of the similar projects in the future.
