苏州地铁深基坑开挖中降水设计问题

摘要

在分析总结苏州地铁4号线多个深基坑降水工程的基础上，对管井设计与管井构造的要求及设计要点进行了研究，并探讨了降水井设计的风险与控制措施，为类似工程施工设计积累了经验。%Based on analyzing and summarizing various deep foundation precipitation engineering of Suzhou subway line No. 4,the paper studies pipe well design and pipe well structure demands and design points,and explores precipitation well design risks and control measures,which has accumulated experience for similar engineering construction design.
