摘要
苏通大桥地处长江入海口,其跨径为1088m,由于受季风等气候条件的影响,使得斜拉索振动成为一个必须解决的工程难题,通过在斜拉索锚固端附近横向安装机械阻尼器以起到减振效果。文章主要介绍了斜拉索减振阻尼器的结构及减振机理。
Sutong bridge is located in the estuary of Yangtze river with the main span of 1088 meter. Because of the effects of monsoon climate, stayed cable vibration is a project difficulty which has to be solved. One of the most vibration common damping measures is to install mechanical damping device near the anchorage zone of stayed cable. This paper introduces the structure and vibration damping mechanism of the damping.
