摘　　要：两墙合一地下连续墙可以节省大量临时支护结构,常被应用于超深地下结构中。因其同时作为临时围护结构与永久地下室外墙,需同时满足施工阶段和正常使用阶段防水抗渗及耐久性的要求。本研究结合具体工程实例分析,介绍了在设计两墙合一连续墙时对裂缝宽度的辩证分析与处理措施,论述了其在设计和施工中需重点考虑的防水抗渗措施,可为类似工程设计和施工提供经济性与合理性等借鉴。The 2-in-1 underground continuous wall is often used in ultra-deep underground structures,as a lot of temporary support structures can be eliminated.Since the continuous wall is used as the temporary enclosure and exterior wall of a permanent basement,it should meet the requirements for waterproofing,impermeability and durability in construction and normal operation.Based on the analysis of specific engineering examples,this study introduces how to conduct dialectical analysis and take corrective actions to control the crack width of 2-in-1 continuous walls,and discusses the waterproofing and impermeability measures to be considered in design and construction,in order to provide a reference for economical and reasonable design and construction of similar projects.
