Abstract:

Submerged floating tunnel (SFT) is a kind of innovative structure used to cross great rivers, large lakes, bays and straits. Submerged floating tunnels possess the duofeatures of tunnels and offshore structures. In this paper, the concept and properties of submerged floating tunnels, the stateoftheart of studies on submerged floating tunnels, especially the dynamic analysis on the interaction between the submerged floating tunnel structures and the surrounding aqueous environment are set forth in brief.
