Expansive Soil (ES) usually referred to as Black cotton soil is found within the central a part of India and covers around 20 % of mainland area. Expansive soils are soils that have large volume modification associated with changes in water contents. The fact that expansive soils are a major engineering downside makes their study a very important research aspect due to the accruing cost concerned in terms of economic loss once construction is undertaken Granular pile anchors GPA are one among the recent innovative foundation techniques devised for mitigating the issues expose by swelling clay beds. This analysis of pull-out behaviour of granular pile anchor (GPA) in expansive clay bed is with two cases. First case is to test single pile of different lengths and diameters to check the pull-out behaviour and in second case 5 piles are arranged in group in such a way to check the pull-out behaviour of only central pile while other four piles are not tested for pull-out. In both the cases we are pulling out on single pile but the difference is in both the cases is that we are checking the behaviour of single pile with no surrounding piles but in second case piles are arranged in group in such a way that four surrounded piles are spaced at a centre to centre spacing of 2D (D=dia of pile) in square pattern while checking the pull-out behaviour of centre pile. The pull-out behaviour of piles in every case is compared with experimental results as already done in experimentation. This analysis is done by using PLAXIS 3D software.
