摘　　要：铺架施工是铁路建设中的一个关键环节,根据与既有线接轨点位置、线下工程施工进度、铺轨基地位置等因素,铺架施工可采取单向铺架、两头铺架和多头铺架等方式。但其施工进度受线下单位作业面移交制约,尤其是单向铺架施工。基于此,文章以新建铁路广州枢纽东北货车外绕线单向铺架施工面临作业面移交不连续情况为例,对两种铺架施工方案进行比选,研究成果可对其他类似工程起到借鉴作用。The laying and erecting construction is a key link in railway construction.According to the location of the connection point with the existing line,the construction progress of the offline project,the location of the track laying base and other factors,the laying and erecting construction can adopt one-way laying,two-end laying and multi-end laying.However,its construction progress is restricted by the delivery of working face of offline units,especially the oneway laying construction.Based on this,this paper takes the discontinuous delivery of the working face in the one-way laying and erecting construction of the northeast freight car outer winding line in the newly built railway Guangzhou hub as an example to compare and select two laying and erecting construction schemes.The research results can serve as a reference for other similar projects.
