摘要
本文对深圳地铁2号线轨道减振降噪技术的应用情况进行了详细的介绍。其中,对国内地铁无碴轨道上首次试铺应用的隔离式减振垫轨道技术的减振原理、设计方案、施工方法及减振效果实测等进行了分析和探讨。通过实测,隔离式减振垫轨道结构的减振效果满足设计理论分析的要求。
This paper gives a detailed introduction to the track vibration and noise reducing technologies used in Shenzhen Metro Line 2.It highlights the isolation damping pad which is first used on ballastless track of metro line in China,including its vibration reducing principle,design scheme,construction method,and site measurement of damping effect.The site measured data show that the vibration reducing effect of the track structure of isolation damping pad meets the requirement of theoretical analysis.
