"Field Installation Effects of Stone Columns on Load Settlement Charact" by Sudip Basack, Sanjay Nimbalkar et al.
Soft-soil reinforcement with stone columns is a popular ground improvement method. Installation of columns modifies the surrounding soft soil properties; this phenomenon is termed "smear."Although several previous investigations were carried out on smear zone characterization, appropriate field-based studies are limited. The authors performed field-based investigations to quantify the installation effects by collecting a series of undisturbed soil samples from a reinforced soft ground site with newly installed stone columns and conducting laboratory testing followed by nonlinear regr...
