摘　　要：随着城市建设高速发展,用地日益紧张,建设工程不断向深基坑的趋势发展,本工程以北支江水上运动中心项目地下室基坑支护和降水工程为例,介绍止水帷幕-重力坝组合支护方式在基坑工程中的应用及其施工方法,总结基坑支护在EPC项目实施过程中的设计优化及施工质量控制要点,经施工验证,可以达到支护、止水和保证基坑施工安全的目的。With the rapid development of urban construction and the increasingly tense land use,the construction project continues to develop towards deep foundation pit,this paper takes the basement foundation pit support and dewatering engineering of Beizhijiang water sports center project as an example,introduces the application and construction method of curtain for cutting off water-gravity dam combined support method in foundation pit engineering,summarizes the design optimization and construction quality control points of foundation pit support in the implementation process of EPC project.After construction verification,after construction verification,water stop and foundation pit construction safety can be achieved.

关 键 词：基坑支护 止水帷幕 重力坝 设计优化 质量控制
