Experimental investigation of single piles and pile groups of triangular pattern (2x1 piles), diamond pattern (2x2 piles) and square pattern (2x2 piles) pile groups have been carried out using the model piles of cylindrical and belled shaped. The piles were made up of concrete (M20) , having diameter of 20mm and of varying length 360mm , 400mm and 440mm. The length to diameter (l/d) ratio have been kept 18, 20 and 22. A total of 24 sets of experiments were carried out. All the piles and corresponding pile groups were tested under vertical uplift loading. Spacing between the two piles in various pile groups was kept three times the piles diameter (3d) in all experiments. The model piles were tested in dry sand bed. Based on the experimental results, behavior of uplift capacity for different piles and pile groups of cylindrical and belled shaped, effect of base enlargement, effect of grouping of piles are discussed in this paper.
