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。
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。
