随着中国综合国力和造桥技术的不断提高,结构新颖、外形美观的桥梁不断出现。南昌英雄大桥采用独柱斜塔扭索面钢混结合斜拉桥,在桥塔造型、斜拉索布置、桥梁施工等方面较普通斜拉桥都有很多的创新。该文对英雄大桥桥塔结构设计、索塔锚固区局部应力分析、斜塔施工过程中关键问题控制、优化等方面进行详细介绍,以期对类似结构设计提供参考。
With the continuous improvement of China’s comprehensive national strength and bridge-building technology, bridges with novel structure and beautiful appearance continue to emerge. Nanchang Hero Bridge using a single column of the tower twisted face twisted steel cable stayed bridge in the tower shape, stay cable arrangement, construction of bridges than the ordinary cable-stayed bridge has a lot of innovation. This paper introduces the design of the bridge structure of Heroes’ Bridge, the local stress analysis of the anchorage zone of the tower, the control and optimization of the key problems in the construction of the tower, and so on, in the hope of providing references for the design of similar structures.
