摘　　要：介绍了潜浮式倒悬索跨海大桥这一新桥型的结构形式和工作原理,探讨了潜浮式倒悬索跨海大桥的施工技术,提出了具体的施工方法和详细的步骤,内容包括桩基、承台、桥墩、锚碇、索系和主梁,讨论了施工难点及施工方法的可行性。Submerged floating reverse suspended cable sea-crossing bridge is a new type of bridge. The paper not only introduced its structure form and working principle but also made a exploration on its construction techniques. And it also offered means and steps of construction in detail. The main content includes pile foundations, cushion caps, piers, anchors, suspended cable system and main girder. Technique difficulties are also discussed in this paper, The construction method discussed was of preferable feasibility. Furthermore, its application will both be beneficial to the development of submerged floating reverse suspended cable sea-crossing bridge and be practically valuable to the con- struction of sea-crossing tubes.
