Abstract

In order to analyze dynamic response of submerged floating tunnel (SFT) in flow field under vortex-induced vibration, equations of motion control of submerged floating tunnel tube-tether were derived by Hamilton variation principle. Considering nonlinear coupling effect between the axial and transverse vibrations of tether, the dynamic response model of submerged floating tunnel was presented. Considering the influence of in-line vortex-induced vibration of tether, equations of motion control in time domain were solved. The calculated results show that if the tether slenderness ratio is large enough, the coupling effect between axial and transversal vibrations of tether can not be ignored. When the in-line vortex-induced vibration of tether occurs, the responses of SFT in surge and roll directions increase obviously, but the heave response is almost invariant.
