Effect of overlap distance and chord angle on performance of overlapping soil-cement columns (2017)
Journal Article
Abbey, S. J., Ngambi, S., & Olubanwo, A. O. (2017). Effect of overlap distance and chord angle on performance of overlapping soil-cement columns

The stress distribution in deep mixing improved columns is affected by cement content and in-situ soil properties of the surrounding soil. Group of cement improved soil column can be overlapped to form a shear wall which can support side slopes of em...
