Stone columns have been widely used to increase the load-carrying capacity of the ground and effectively reduce the settlement on soft clay beds and loose sandy soil. However, the stone column improves the ground condition in compressive load and is unable to withstand tensile or uplift force. The Granular Anchor Pile foundation (GAP) technique is a slight modification over conventional granular piles used to sustain the uplift force. The GAP is provided with an anchorage system through an anchor rod that is connected to the anchor plate at the bottom of the pile. In the present study, the behavior of GAP constructed in sandy soil subjected to uplift loading is performed using a laboratory model test. The load–displacement behavior of the GAP is examined. The effect of varied L/D ratio and constant diameter of 50 mm of GAP has been studied. The findings from the current study show the improvement in the ultimate uplift capacity of the GAP with the increment in the L/D ratio. The maximum percentage of improvement in the pullout capacity of the pile has been observed for L/D ratio 6. An increment in the L/D ratio beyond 12 shows a reduction in the ultimate pullout load.
