Expansive soil shows large volume change behavior when subjected to different moisture condition. Uplift of light weight structures occurs due to the swelling of soil. To increase the uplift resistance granular pile, anchors are used with and without reinforcement. Model studies are performed on granular piles anchors to check the pullout resistance. Study include testing of granular pile anchors with and without reinforcement in unsaturated and saturated condition. Black cotton soil was collected from Palakkad district. The initial test on soil was done and it is found that the soil is silty clay. A model test tank of 50cmx50cmx60cm dimensions are made. Pullout test is done to determine the pullout capacity of GPA, pullout test is done with different l/d ratio in unsaturated condition with and without reinforcement. From the result obtained it is seen that, when the l/d ratio increases the pullout resistance also increases and the maximum result obtained is 99.7N for l/d ratio equal to 2.5 without reinforcement and 102.24N for l/d ratio with 2.5 with reinforcement.
