摘　　要：介绍了石家庄铁路枢纽内相关工程的结构形式,重点研究了隧道口附近无砟轨道至有砟轨道的过渡段设计,提出了有、无砟轨道过渡段设计过程中应注意的问题。The relevant engineering＇ s structural form of ShiJiaZhuang railroad terminal is introduced. The transition section between ballastless track and ballasted track near the tunnel opening is a priority research area in the paper. Matters which need attention during the designing of changeover portion between subgrade and tunnel are proposed as well.
