摘　　要：针对旧有铁路线路进行无缝化改造,需要采用换铺法,实现线路合理焊接。基于这种认识,文章结合工程实例,对无缝线路换铺施工方法展开了分析,对换铺施工过程中各个环节进行了探讨,并重点说明了线路应力放散与锁定施工方法,以便使工程施工质量得到保证,从而为类似工程建设提供参考。For the seamless transformation of the old railway lines,it is necessary to adopt the method of changing paving to realize the reasonable welding of the lines.Based on this understanding,combined with an engineering example,this paper analyzes the replacement construction method of jointless track,probes into each link in the process of replacement construction,and focuses on the construction method of line stress release and locking,so as to ensure the construction quality of the project and provide a reference for the construction of similar projects.

关 键 词：无缝线路 换铺施工 应力放散与锁定
