%X The engineering analysis method for vortex-induced transverse vibration of submerged floating tunnel(SFT) tether is presented,based on the modified wake oscillator model.The effects of specific gravity ratio and the shear current's characteristics on the vortex-induced vibration of tether are investigated. The calculated results show that the distribution of lock-in regions and the vortex-induced vibration of tether vary with the specific gravity ratios of SFT.The increase of the shear parameter makes the amplitude of vortex-induced vibration decrease.Furthermore,if the shear current is replaced by the uniform current to calculate the vortex-induced vibration of tether,its response amplitude may be overestimated.
