摘　　要：浮置板轨道因其具有自振频率低、减振效果好等优点,在近几年中,被成功应用到我国的城市轨道交通系统中。简要分析了浮置板轨道的隔振原理,对其分类和应用等进行了评述,并根据现场实测数据重点分析了浮置板轨道的减振性能和平稳性,为轨道交通的减振设计提供参考。Floating slab track has low natural frequency and good damping effect, which has been made full use in foreign countries for decades and in China for several years. In this paper, the vibration isolation principle, the categories and the application of the floating slab track are introduced. And the damping performance and running stability are analyzed in details based on the measured data. The conclusion can orovide reference for vibration isolation design of the urban mass transit.
