Abstract
Nowadays, geotechnical engineers are facing the problem of soft ground, which results into 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. This paper addresses the practical real-time results of laboratory model of single CFG pile. Moreover, the comparative evaluation between simulation results (i.e., numerical analysis) and laboratory model has been carried out considering variation in parameters such as diameter of the CFG pile, length-to-diameter ratio of CFG pile, and gravel particle size. The results obtained from this analysis clearly prove superiority of CFG pile over soft ground in terms of enhancing load carrying capacity.
