摘要
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 development of bridge design technique and construction methods, the span capacity of cable-stayed bridge can reach over 1 000 meters. The selection of structural system has been an important problem. Through the example of a 730 m-span cable-stayed bridge, different structure systems are introduced and compared, meanwhile the analysis process and results are discussed.
