摘　　要：水泥深层搅拌桩是对沿海潮间带淤泥滩地进行软基处理的一种有效形式。结合工程实例,针对经过淤泥吹填砂的地基,采用桩长为9.0m、12.0m和15.0m的3种型号水泥深层搅拌桩处理软基。讨论水泥深层搅拌桩的桩-土作用机理、设计参数、施工工艺流程以及质量检验评定。实践表明,该方法能够在依托工程中取得较好的加固效果。The cement deep mixing pile is on the coastal intertidal mud beach is an effective way to deal with soft foundation,relying on the project instance,after mudhydraulic fill sand foundation,the use of pile length 9 meters,12 meters and 15 meters of 3types of deep cement mixing pile in soft foundation treatment,discusses the cement deep mixing the pile-soil interaction mechanism,design parameter,construction process and quality inspection and evaluation,engineering practice shows that,the method has a good reinforcement effect in relying on engineering.
