摘要
本项目为一座主跨500m双塔双索面钢箱梁斜拉桥,跨径布置为50+180+500+180+50=960m,采用独柱形全钢索塔,分离式钢箱梁。大跨径斜拉桥采用独柱形全钢索塔在国内尚属首例,本文介绍了该桥的结构分析,包括总体静力分析、抗震及抗风分析研究。
The project is a double tower double cable plane steel box girder cable-stayed bridge with the main span of500m,and the span arrangement is50+180+500+180+50=960m.The single-column-shaped steel tower and the separate steel box girder are adopted in this bridge.It is the first time that single-column-shaped steel tower is adopted in large-span cable-stayed bridge in China.In this paper,the structural performance analyses of this bridge including static analysis,seismic and wind resistant analysis are introduced.
