Numerical modeling of the impact of stone columns on liquefaction

Some regions have liquefaction potential due to their geological set up. Most of the structures built on the liquefiable soil severely settled or tilted besides the structural damages. To re-accommodate these structures, it is necessary to strengthen them besides improve their ground conditions. Then, it may be possible to avoid probable damages caused by liquefaction and use them again safely. In this study, application of modified dry bottom feed stone column as one of the dominant ground improvement methods in the region was introduced. Also, a numerical analysis is carried out to check its performance with respect to displacements. According to numerical results, significant improvements were obtained in terms of displacements.
