N2 - This paper studies the performance improvement due to the presence of geocell layer at the base of the embankment over soft clay deposit. The experimental study was carried out by conducting tests on model embankments overlying soft clay with reinforcement by geocell mattress at the interface between the earthen embankment and soft clay foundation bed, by varying its parameters like aspect ratio (pocket size), and type of infill material. Experiments were also carried out for unreinforced foundation soil beneath the earthen embankment, to show comparative performance and ground improvement due to soil reinforcement using geocell mattress. Test results indicated a considerable percentage reduction in settlements, lateral deformations and percentage increase in ultimate capacity of geocell reinforced embankments, over unreinforced embankment. The test results were also validated using finite element analyses of geocell reinforced foundation over unreinforced foundation.
