Abstract
Coupled dynamic analyses of 900-m-long SFT (submerged floating tunnel) are conducted for various system parameters and random waves. The SFT dynamics between the clamped-clamped fixed-end conditions are caused by elastic modes, and thus hydro-elasticity simulation program has been modeled, from which various elastic modes and wet natural frequencies are identified. Parametric studies are conducted to investigate SFT horizontal and vertical motions and mooring tensions with varying SFT bending stiffness, mooring interval, mooring material, and 100-yr-storm-wave conditions. The BWR (buoyancy to weight ratio) and water depth are fixed to be 1.3 and 80 m. Various nonlinear phenomena including larger downward motion and the corresponding mooring snap loading are observed and discussed.
