摘　　要：新建郑济铁路无砟轨道采用我国自主研发的CRTSⅢ型板式无砟轨道。着重介绍CRTSⅢ型板式无砟轨道混凝土底座施工、中间隔离层及弹性垫层施工、限位凹槽周边弹性垫层施工及轨道板粗铺和精调,分析了自密实混凝土灌注等施工工序的施工要点、遇到的问题及相应的解决措施,为在建工程和其他线路工程提供参考。The newly-built Zhengji Railway ballastless track adopts CRTSⅢslab ballastless track independently developed by China.This article focuses on the construction of the concrete base of CRTSⅢslab ballastless track,the construction of the intermediate isolation layer and the elastic cushion,the construction of the elastic cushion around the limit groove,and the rough laying and fine adjustment of the track slab.The construction points of self-compacting concrete pouring and other construction procedures,as well as problems and corresponding solutions,are intended to provide references for construction in progress and other line projects.
