Effects of Densification and Stiffening on Liquefaction Risk of Reinforced Soil by Stone Columns
AbstractThe installation of stone columns is widely adopted to prevent liquefaction. The main improvement mechanisms of stone columns as a liquefaction countermeasure are drainage, stiffening, and densification. This paper investigates the effectiveness of stone columns as a liquefaction remediation. Twenty-four case studies, in which SPT and CPT tests are performed before and after stone column reinforcement, are used as a basis of the research. Densification and stiffening mechanisms are investigated and their individual and combined effects are analyzed. Comparative results indicate that considering the densification and stiffening effects considerably improve the assessment of liquefaction potential of reinforced soil by stone columns.
