摘要	Recently on a previously unknown phenomenon in vortex-induced vibrations (VIV) of the flexible structures with large aspect ratio (length to diameter) was discovered in field experiments, which shows that traveling wave rather than standing wave dominates the response of VIV. In this paper propagation of CF and IL responses in Submerged Floating Tunnel (SFT) has been simulated by using a modified wake oscillator, in which wake diffusion and variation of tension along the axis of tether are considered. The dominance of travelling wave in VIV has been predated. Finally the effect of the dominance of traveling wave on VIV of SFT tethers under shear flows has been addressed.
