摘　　要：软弱破碎地层盾构接收施工风险较大,常用冻结法进行地基加固处理。以上海市轨道交通14号线云山路站端头井盾构接收冻结加固项目为背景,探讨在软弱富水地层中采用杯型冻结壁进行地层加固的盾构接收工艺及施工要点,保障盾构接收顺利完成,可为类似工程施工提供参考。The risk of shield receiving construction in soft and broken stratum is large,and the freezing method is often used for foundation reinforcement.Based on the project of shield receiving and freezing reinforcement of Yunshan Road station end shaft of Shanghai rail transit line 14,this paper discusses the shield receiving technology and construction points of using cup-shaped frozen wall for stratum reinforcement in soft water rich stratum,so as to ensure the smooth completion of shield receiving,which can provide reference for similar engineering construction.
