斜拉索粘滞阻尼器能抑制斜拉索振动，可作为斜拉索永久抑振措施。结合粘滞阻尼器理论原理，针对嘉绍大桥主航道桥斜拉索设计了阻尼器性能参数，并开发了阻尼器产品。对阻尼器进行性能试验及现场减振效果测试，结果表明：阻尼器性能稳定，各项性能指标均满足设计要求；实测对数衰减率达到6％以上，与理论值变化规律基本一致，具有良好的减振效果。

Viscous dampers was able to curb the vibration of stay cables ,which can be taken as the permanent vibration control measure for stay cables .Combined with the theories of the viscous dampers ,the performance parameters of the dampers for stay cables of the main naviga-tional channel bridge of Jiashao Bridge were designed and the viscous dampers were developed . The dampers were checked by the performance testing and field vibration efficiency testing .The results of the testings demonstrated that the dampers showed stable performance ,all the per-formance indexes could meet the design requirements .The measured logarithmic decrement was above 6% ,basically in compliance with the changing rule of the theoretical values ,proving that the dampers have sound vibration damping effect .
