Abstract

In this paper, the behaviour of a 3D soil-structure system of square footing pad constructed on the ground reinforced with jet grouted columns was studied with 3D models using the commercially available FLAC 3D version 3.1 finite difference Code. The isolated shallow square footing pad supporting a typical building was constructed on the ground susceptible to liquefaction and on the reinforced ground with stiff jet grouted column rows. The results showed that ground reinforced with one row of continuously overlapping columns (forming a lattice) adjacent to the four sides of footing pad can be effectively applied to reduce the liquefaction-induced large settlements to the tolerable limits.
