中文摘要:针对苏州中心项目基坑临近地铁侧、隔断承压水的特点，采用超深地连墙进行基坑围护。根据工程重点、难点以及质量控制要求，对地下连续墙成槽过程中的护壁泥浆问题进行了分析研究，提出了泥浆配制、参数控制、泥浆处理的成套方案。现场实际应用表明，所研究的优质护壁泥浆在本工程地连墙的施工中是行之有效的。

Research on Slurry in Ultra Deep Underground Continuous Wall for Deep Foundation Pit Bracing
Abstract:According to the characteristics of the pit supporting in Suzhou Center project, which is near the subway and severing the confined water, ultra deep underground continuous wall was adopted to brace the foundation pit. Aimed to the engineering key, difficult point and the quality control requirement, the research and analysis were made on the slurry in groove constructing process for the ultra deep underground continuous wall. A whole set of slurry preparation, parameter control and slurry treatment were presented. The practice showed the slurry is very feasible in the underground continuous wall engineering.
