This paper presents the experimental and numerical procedure for analyzing the shear load capacity of Geosynthetic Encased Stone Columns (GESC). Past studies have mainly focused to understand the vertical load capacity of GESC. However, these columns may also be subjected to significant amount of shear loading such as near the toe of high embankments and retaining walls, etc. The shear load capacity of the GESC depends on the diameter of the column, over burden pressure acting on the soil, geosynthetic strength properties etc. In order to analyze the shear load capacity of GESC laboratory tests were performed within a large shear box with GESC. The experimental results were validated using FLAC3D software. The results showed that the geosynthetic encasement provides an additional confinement to the aggregates which leads to improvement in the performance of GESC.
