以Iwan改进的尾流振子模型为基础，给出了剪切流中水中悬浮隧道锚索横向涡激振动的工程分析方法，分析了悬浮隧道重浮比以及剪切流特性对锚索涡激响应的影响．计算结果表明，悬浮隧道重浮比的改变，使锚索各阶模态的频锁区域分布发生变化，从而改变了结构的涡激振动响应；剪切流陡度参数的增大会使锚索涡激响应的幅值减小，若使用均匀流场代替剪切流场计算悬浮隧道锚索的涡激振动，会过高估计其响应幅值． |

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. |
