- Submerged Floating Tunnel
Submerged floating tunnel (SFT) is considered as an alternative method for resolving the limitations of transportation caused by geographical positions. Although SFT technologies are very challenging in many aspects, it can be more cost effective and safer than under-seabed tunnels especially in seismically active regions. Engineers seeking to build SFTs are required to analyze their dynamic motions under various scenarios and reflect those analysis results for the design processes. The aim of the research is conducted numerical simulations of SFTs with vertical and inclined mooring system under sea waves and/or seismic excitations. Both regular and irregular water waves and seismic motions are inputted. In the earthquake cases, the transmissibility of the ground motions through two types of mooring lines to the SFT responses is investigated.
