摘　　要：针对现有减振方法对拉索振动控制的不足,尝试利用调谐液体阻尼器(TLD)抑制拉索振动。首先设计了TLD模型,并进行了TLD单体试验,其次对Cable-TLD组合系统进行了试验研究。研究表明利用TLD抑制拉索振动是可行的。其研究为同时控制拉索面内外复杂耦合振动提供了一种新思路。According to the deficiency of the vibration control of the cable in the existing vibration reduction meth- od, trying to use tuned liquid damper （TLD） to suppress the vibration of the stay cable. First, experimental model of TLD is designed, and the TLD monomer test is carried out. Then the experimental research on the Cable - TLD composite system is carried out. The study shows that it is feasible to use TLD to suppress the cable vibration. The research results provide a new method for the simultaneous control of the inside and outside complex coupling vibra- tion of stay cable.
