Undrained shear strength of soft clay reinforced with encapsulated stone dust columns

Purpose: The stone dust column was used to strengthen the sample and had a significant effect on improving the shear strength of the kaolin clay. The application of stone columns, which can improve the overall carrying capacity of soft clay as well as lessen the settlement of buildings built on it,...
