“…The increase of strengthening factor, µ r , from 1 to 5 increases the radial displacement impact factor, i r , and decreases along the depth of GP which shows the effect of strengthening in upper part. For strengthening factor, µ r =1 (unstrengthened) GP, the results are validated with the Madhav et al [21] and found the variation trends are same. With the increase in comparative size of raft, d r / d p, the radial displacement impact factor, i r , decreases at the top.…”

In today’s time, construction is the main key for development of any nation, but land resources are getting deplete. Thus, construction on compressible soil is left as a choice. Stone columns or granular piles (GPs) are broadly used to advance the bearing capacity of crummy ground and lessen the displacement of constructionserected on them. GP is the most efficient and cheap for ground improvement. Analysis of single partially strengthened (SPS) floating granular piled raft is presented in this paper in terms of several normalized aspects like vertical and radial displacement impact factors, settlement impact factor (SIF) for any depth, the normalized GP–soil interface shear and radial stresses, the load ratio, i.e., the percentage of the load taken by the GP and raft to the total load, and the normalized contact pressure distribution below the raft, which are evaluated for SPS floating granular piled raft. The SIF for top of GP is noticed to decline with the surge in the values of the strengthening parameters. The interfacial shear stresses get reorganized along the length of the GP.

“…Results obtained in this analysis have been validated with those of Madhav et al (2009) for rigid raft on a single compressible unstrengthened floating pile analyses with or without radial displacement compatibility for radial displacement. The agreement has been very close as shown in Fig.…”

“…Alamgir et al [6] proposed the deformation behaviour of a soft ground reinforced with stone columns installed in a group, using a simple analytical approach. Madhav et al [7] discussed about the settlement and load distribution in a granular piled raft. Zhang et al [8] presented the settlement calculation of a foundation of composites reinforced with stone column.…”

Ground improvement with granular piles increases the load-carrying capacity, reduces the settlement of foundations built on the reinforced ground and is also a good alternative to concrete pile. Granular piles or stone columns are composed of granular material, such as crushed stone or coarse dense sand. An analytical approach based on the continuum approach is presented for the non-linear behaviour of the granular pile. The formulation for pile element displacement is done considering the non-homogeneity of the granular pile as it reflects the true behaviour and also accounts for the changes in the state of the granular pile due to installation, stiffening and improvement effects. The present study shows that the settlement influence factor for an end-bearing granular pile decreases with increase in the relative stiffness of the bearing stratum. The settlement influence factor decreases with increase in linear and non-linear non-homogeneity parameters for all values of relative length. For a shorter pile, the rate of decrease of the settlement influence factor is greater in comparison to that for a longer pile. Shear stress at the soil–granular pile interface reduces in the upper compressible portion of the granular pile and increases in the lower stiffer portion of the granular pile due to the non-homogeneity of an end-bearing granular pile.

“…Several literature pertaining to the behavior of footings resting on fully penetrated granular piles are found (e.g., [2][3][4][5][6][7][8][9][10][11][12]. But, a little number of literature concerning the behavior of footings resting on floating granular piles are found (e.g., [13][14][15][16][17][18][19][20][21][22].…”
