摘要
城市轨道交通减振设计历来是轨道专业设计的重点内容。结合广州地铁4号线北延段的工程实际与环评报告书,对轨道中等减振设计方案进行比选,论述GJ-Ⅲ型减振扣件、LORD减振扣件和减振器扣件的结构组成、减振效果、优缺点和经济性,推荐采用GJ-Ⅲ型减振扣件方案,可为其他城市地铁轨道中等减振设计提供参考。
Vibration-damping design of urban rail transit has always been the key content in track engineering design.This article,combining with the actual project of North Extension Section of Guangzhou Metro Line 4 and the EIA report,carries out comparison and selection for the medium vibration-damping design schemes of the track,also discourses respectively the GJ-Ⅲ vibration-damping fastener,LORD fastener and the shock-absorber fastener from the aspects of the structure composition,vibration-damping effect,advantages and disadvantage and economical efficiency.Finally,this article recommends the scheme of GJ-Ⅲ vibration-damping fastener.This article also provides a reference for other cities on the medium vibration damping design of the metro track.
