摘要
针对具体工程实例分析了挖除换填、排水固结法、水泥搅拌桩法、碎石桩、CFG桩、强夯置换法等软土地基处理方法的适用性及优缺点,从而确定采用强夯置换法作为本项目的处理方案,并对强夯置换的置换参数、试夯、质量检验等进行了详细设计,得出了在软土地基处理中应重视方案比选及强夯置换法是处理浅层软土的一种行之有效的方法等结论。
Aiming at engineering practice,the applicability and relative merits of soft soil foundation treatment methods such as excavation replacement,drainage consolidation,cement mixing pile,gravel pile,CFG pile and dynamic compaction replacement are analyzed and then dynamic compaction replacement is selected as the treatment method for this project.The replacement parameters,trial tamping and quality test are designed in detail.It is concluded that scheme selection is important in soft soil foundation treatment and dynamic compaction replacement is an effective method for treatment of soft soil in superficial layers.
