Dynamic Response of a Submerged Floating Tunnel Subject to Hydraulic Loading: Numerical Modelling for Engineering Design

The submerged floating tunnel (SFT), also called an Archimedes Bridge, is a new type of infrastructure for wide and deep sea-crossings, regarded as one of the alternatives to bored and immersed tunnels and bridges. It is afloat in water employing its buoyancy and a support system to balance its self-weight. However, no prototype SFT has yet been...

Response of a submerged floating tunnel subject to flow-induced vibration

In order to assess the dynamic performance of a submerged floating tunnel (SFT) subject to flow-induced vibration (FIV) conditions in a practical engineering application, a one-way fluid–structure interaction (FSI) model consisting of multi-scale hydrodynamic solvers combined with the finite element method (FEM) is established. A typical long...
