摘　　要：本文根据工程实例介绍了深层搅拌桩在基坑止水帷幕墙中应用,并简述了其计算方法。工程实践表明,深层搅拌桩与周围土体共同作用形成的水泥土挡墙具有安全可靠,无噪音,综合工期短,无污染等优点。Formed by the forced mixing of proportioned cement mortar and foundation soil by special machine deep in the foundation,the water-stopping curtain wall of soil-cement pile can improve the stability of the foundation slope and performance of anti-seepage,thus reaches the objectives of stopping water and retaining soil.Based on the practice in actual project,calculation method of deep mixing piles in water-stopping curtain of foundation pits is introduced.Deep mixing piles combined with surrounding soil forms cement-soil retaining wall. Project practices show that cement-soil retaining wall has advantages of high reliability, lower noise, short construction period and no pollution.
