Combining with Maoling rail welded base engineering design example,this paper discusses the production line. According to general layout condition and existing equipment arrangement. Make a comprehensive comparison on Z type,一 type and U type,three type of production layout scheme,determine the Z type construction scheme,production process layout is reasonable and efficient by practice.%结合茂陵焊轨基地建设工程的设计实例，论述了焊轨基地钢轨生产线的工艺生产流程，结合地形条件及既有设备布置情况，对 Z 字型、一字型及 U 字型三种生产布局方案进行了综合比选，确定了 Z 字型建设方案，经实践证明，Z 字型生产工艺布局合理、作业顺畅。
