随着桥梁设计及施工技术的不断发展,斜拉桥主跨跨径目前已达到千米级,选择怎样的结构体系已成为设计者必须面对的一个关键问题。文中介绍了大跨径斜拉桥结构体系的几种形式,并结合主跨为730 m的双塔钢箱梁斜拉桥结构体系,介绍了分析过程和比较结果。
With the continuous development of bridge design and construction technology, the span of main span of cable-stayed bridge has now reached the kilometer level. The choice of the structural system has become a key issue that designers must face. In this paper, several forms of structural system of long-span cable-stayed bridges are introduced. Combined with the structural system of double-girder steel box girder cable-stayed bridge with main span of 730 m, the analysis process and comparison results are introduced.
