The Deep Mixing Method (DMM), a soil improvement technique, is frequently employed to enhance the strength of soft ground in Delta areas. With extensive urbanization and industrialization in soft clay zones, there has been a substantial increase in the design and construction of infrastructure facilities in recent years. Over the past few decades, comprehensive, well-documented reports have been developed at various stages, covering state-of-the-art techniques for improving ground conditions, design methodologies, and detailed records of the adoption of various methods. Among these methods, Cement Deep Mixing (CDM) columns, formed by DMM, emerge as a cost-effective and efficient solution for treating soft soils beneath embankments. This research delves into the configuration of CDM columns embedded in soft ground layers, exploring different dimensions, spacing, and lengths of the CDM columns.
