Numerical Evaluation of Partially Strengthened Floating Granular Pile Raft With Vertical and Radial Displacement Compatibility

Abstract

Abstract 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.
