Results from a series of 3D numerical approach have been presented to study unreinforced and geogrid- reinforced sand bed resting on stone columns-improved soft clay. Influences of the thickness of unreinforced as well as geogrid-reinforced sand bed and the number of geogrid reinforcement on the performance of stone columns-improved soft clay bed have also been investigad. The inclution of geogrid layer within sand bed further decreases the settlement of soil and also decreases lateral deformation. Single layer reinforcement with stone columns is very effective to reduce the total settlement and bulging diameter.
