摘　　要：本文结合既有湘桂线改线工程实例,介绍了既有线封锁高抬道大拨接施工的工艺方法,并对轨道施工技术措施进行了探讨。工程实践证明,该施工技术可为同类铁路改造施工提供借鉴与参考。Combining with the example of the existing Hunan-Guangxi line rerouting project,this paper introduces the technology and method of the existing line blockage and high-lift road and large-scale connection construction,and discusses the technical measures of track construction.Engineering practice has proved that this construction technology can provide reference for similar railway reconstruction construction.
