Abstract
A series of laboratory load tests were carried out to investigate the effect of geometrical dimensions of a handmade geocell on the ultimate bearing capacity of geocell-reinforced sand beds. The parameters considered in the study include the geocell placement depth from the base of the footing (u), equivalent diameter of geocell pocket (d), height of geocell reinforcement (h), width of geocell reinforcement (b) and relative density of the sand (Dr). A multiple regression equation was developed by analysing the experimental results for estimating the ultimate bearing capacity of the reinforced sand bed. The equation proposed was verified against empirical equation reported by other researchers. The statistical analysis of the model test data shows that the parameters studied have a significant influence on the performance of the footing in terms of its bearing capacity and settlement. The regression equation developed in this investigation is reasonably good in predicting the bearing capacity of a square footing supported on geocell-reinforced sand beds.
