摘要：During the course of the development over the past few decades, at various stages, well documented stage of the art reports dealing with the techniques of improving ground conditions, design methodology, and specific records of adopting different methods. Among these methods, Cement Deep Mixing (CDM) columns formed by DMM is an economical and effective methods to treat the soft soils under embankment. In this research the configuration of the CDM column, which is embedded in the soft ground layers, is investigated for different sizes of diameter, spacing and length of CDM column. By this research, a new method to find out the optimum configuration using the formula in the current design is proposed as the Simplified Design Method. The soil improvement technique, called Deep Mixing Method (DMM), is often applied for improve the strength of the treated soft ground in Delta areas. In recent years design and construction of infrastructure facilities arising due to extensive urbanization and industrialization in soft clay zones has considerably increased.
