The objective of this paper is to study the effectiveness of stone column reinforcement in mitigating the liquefaction potential through the evaluation of maximum pore water pressure ratio (ru). Based on ru the liquefaction potential can be assessed. Liquefaction potential of a site with three sand layers (Layer 1: Dr ≈ 60%, 2.0 m thick; Layer 2: Dr ≈ 35–40%, 6.0 m thick; Layer 3: Dr ≈ 90%, 2.0 m thick) was studied by a finite element approach, which is an effective stress-based elasto-plastic UBCSAND 2D model. A numerical study was conducted with simulation of two different site conditions, i.e., (1) Simulation of sand layers without stone columns and (2) simulation of sand layers with stone columns as drainage path. A surcharge load of 80 kPa and a cyclic loading were applied for both conditions. The study further examines the behavior of the soil in both the cases to assess its susceptibility to liquefaction at different depths and along with acceleration profile with time. Analysis of excess pore water pressure generation over time aligns with the findings of Demir and Ozener in ASCE, Geotechnical Earthquake Engineering and Soil Dynamics [1].
