Abstract
The multifan jet grouting method of ground improvement was developed to reduce the amount of redundantly improved soil. In this study, we geometrically examined the effectiveness of multifan-shaped columns for lattice- or wall-form ground improvements. Consequently, ground improvement work could be performed more effectively with multifan columns than with oval or round columns. Furthermore, we developed new equipment to construct multifan columns, and conducted field tests to confirm its workability. Consequently, we confirmed our assumption that it is possible to construct multifan-shaped columns for ground improvement.
