.... The most suitable spacing ratio for a submerged floating tunnel (SFT) is 1.5, as it exhibits the lowest response amplitude. The spacing ratio has a significant influence on the response amplitude and frequency, 3D is a transition spacing of the vortex shedding modes, an amplitude modulation phenomenon...

... Abstract The submerged floating tunnel (SFT) is a long tunnel that remains suspended below the water surface at a considerable depth of around 100–150 m and connects to land masses separated by ‘deep’ and vast water bodies. The present study aims to characterize the flow dynamics around...

... Abstract This paper systematically studies the submerged floating tunnel, a concept initially proposed in the 19th century, only sporadically built, but possibly more viable potential in the future. The first part of this paper presents a literature review on submerged floating tunnel concepts...

... Abstract We develop a fully-coupled time-domain hydro-elasticity model for the Submerged Floating Tunnel (SFT) based on the Discrete-Module-Beam (DMB) method. Frequency-domain simulation based on 3D potential theory results in multibody’s hydrodynamic coefficients and excitation forces...
