摘　　要：上海市地铁1号线北延伸一期工程南起上海火车站北端头井,北至外环线泰和路站,其中南段为地下段(新客站北端头井～灵石路北侧),北段为高架一体化结构。南段大部分区间隧道采用盾构法施工,当隧道埋深较浅时(≤4m),在采用明挖法施工暗埋及敞开过渡段后牵出地面,同高架结构相接,就该引道结构的特殊设计作一介绍。The North Extension(Phase Ⅰ)of Shanghai Metro Line No.1 starts from the northern shaft of Shanghai Rail- way Station and ends at Taihe Road Station.The shield drives most parts of the southern underground section (from the northern shaft of Shanghai Railway Station to the north of Linshi Road).When the soil covering is less than 4m,out-cover method is adopted to construct the ramp connecting to viaduct.The structural design of this special structure is introduced in the paper.
