摘　　要：两墙合一的地下连续墙可以节省支护空间,扩大地下室使用面积,在超深地下室设计中常被采用。因其作为永久地下室外墙使用,需要满足防水抗渗的耐久性要求。通过对具体工程实例的分析,论述了永久连续墙在设计和施工中需重点考虑的防水抗渗措施。对类似工程在设计和施工阶段提供有益借鉴。The underground continuous wall with two walls in one can save the support space,make full use of the site and expand the use area of the basement,which is often used in the design of ultra deep basement.Because it is used as the external wall of the permanent basement,it needs to meet the durability requirements of waterproof and impermeability.Based on the analysis of specific engineering examples,the measures of waterproof and impermeability of the permanent continuous wall in the design and construction stages were discussed.It can be used for reference in the design and construction of similar projects.
