摘　　要：文章针对目前广泛应用的减振轨道,提出了插入质量调谐系统的方法,并通过有限元分析研究了结构改造前后的减振性能以及各参数对减振性能的影响,以期为今后城市轨道交通建设起到指导和促进作用。Vibration damping track has been widely used in urban rail transit. In order to further improve the vibration damping performance of track, the effective use of space between track and ballast, the paper puts forward the method of inserting the quality tuning system, and study the infl uence of vibration damping performance of structure before and after the modification and the parameters on the vibration damping performance through fi nite element analysis in order to guide and promote the construction of urban rail transit in the future period.
