Nowadays, geo technical engineers are facing the problem of soft ground, which results in to low bearing capacity and excessive settlement. On contrary, Cement Fly-ash and Gravel (CFG) pile is one of the emerging ground improvement techniques, which can be applied to enhance the load carrying capacity of the soft ground. It also reduces the possibility of settlement associated due to soft ground. CFG pile composite foundation is applied in subsoil treatment widely and successfully. In order to have a further study of this kind of subsoil treatment technology, the influencing factors and calculation methods of the vertical bearing capacity of single CFG pile and the CFG pile composite foundation were discussed respectively. This paper addresses the practical real time results of laboratory model of single CFG pile. The laboratory model has been carried out considering variation in parameters such as diameter of the CFG pile, length to diameter ratio of CFG pile, cushion effect and gravel particle size. The results obtained from this analysis clearly proves superiority of CFG pile over soft ground in terms of enhancing load carrying capacity.
