中文摘要：悬浮隧道锚索是连接悬浮隧道管体与水下基础的重要构件,其在水流作用下可能会发生涡激振动,导致结构疲劳,影响结构安全。因而,研究悬浮隧道锚索涡激振动的抑制方法,具有重要的理论和现实意义。设计了三种抑振装置:螺旋条纹,控制杆和整流罩,采用试验方法研究了其抑振的有效性和适用性。通过试验发现,随着锚索倾斜角度的减小,三种抑振装置的抑振效果均有不同程度的提高,其中以三螺旋线的抑振效果最好且最稳定;随着来流角度的增大,三螺旋线和整流罩的抑振效果会不同程度的提升,但三控制杆对来流角度变化较为复杂;在多参数综合影响下,三螺旋线的抑振性能最好,推荐使用。

外文摘要：The cables are the important components of submerged floating tunnel which connect the tube with the underwater foundation ,but the vortex‐induced vibration of cables will occur under the current that will lead to fatigue and affect the safety . Thus ,the study of VIV suppression method has important theoretical and practical significance .In this paper ,three kinds of vibration suppression devices were presented ：strakes ,control rods and fairings ,of which the validity and applicability were re‐searched by experiments .The results show that the suppression effect of all the three devices will increase to various extents with the decrease of the cable inclination angle and the strakes are the best .As the angle of stream increases ,the suppression effect of strakes and fairings are increased ,but that of the control rods are complicated .Finally ,the strakes are recommended to use because of the best performance in the multi‐parameters researches .
