Abstract
Although actual submerged floating tunnels have not yet been constructed, they are seen as one of the most promising structures for strait crossings. The authors proposed a suitable model for a super-long submerged floating tunnel using the modified Morison's equation even if the phase delay by propagation of earthquake wave should be taken into consideration. As a result of this study, a super-long tunnel of 2km in length were analyzed, and the fundamental characteristics of the response due to earthquakes were obtained.
