2) multi-tower suspension bridges
多塔悬索桥
1.
Compared with the common two-tower suspension bridge with single main span,the main spans of multi-tower suspension bridges can be greatly shortened,and the cables tensional forces,the size of anchorages and also the cost are thus decreased significantly,and it becomes a competitive solution for long and particularly super long span bridges.
与采用中间只有单一主跨跨过的双塔悬索桥相比,多塔悬索桥可以大大减小主跨跨径,显著减小主缆拉力及锚碇规模,其综合造价随之降低,因而成为特大跨径桥梁的一种具有竞争力的桥型方案。
5) multi-tower and multi-span
多塔多跨
1.
Several practical examples of the multi-tower and multi-span suspension bridges that are being constructed,about to be constructed,are being conceptually designed in China and that have different environmental characteristics are presented.
介绍中国大陆几座正在建设和即将开工与正在进行方案设计之中的、各具不同环境特点的多塔多跨悬索桥实例。
6) large span suspension bridge
大跨悬索桥
1.
Research on increasing the air-operated steps of large span suspension bridge flutter critical wind velocity;
提高大跨悬索桥颤振临界风速的气动措施研究
2.
An introduction is given to major issues in design of anchor foundation for large span suspension bridge, and a analysis is given of several commonly-adopted foundation programs.
结合国内外悬索桥锚碇建设经验 ,介绍大跨悬索桥锚碇基础设计与施工中的主要问题 ,对几种常用的基础方案进行分析比
补充资料：悬索桥
| 悬索桥 suspension bridge 特大跨径桥梁主要形式之一。又称吊桥。一般认为，跨径600米以上应优先考虑悬索桥方案。 主要承重结构由缆索、桥塔和锚碇组成的桥梁。缆索通过两座桥塔顶两端延伸至桥台后锚固。桥面系和加劲梁通过吊杆悬挂在悬索上。具有合理的受力形式，主要承重构件——悬索受拉，无弯曲和疲劳而引起的应力折减，可采用高强钢丝制成。是所有桥梁体系中跨越能力最大的、跨径超过1000米的唯一桥式。英国亨伯桥主跨1410.8米，为当前世界上跨度最大的公路桥。西藏自治区达孜桥主跨415米，桥长541米，悬索一端锚于岩石中，仅设一座索塔，1984年建成，是中国最大的悬索桥。
