Analytical Study for a Set of Partially Strengthened End-Bearing Granular Piles

A. Jitendra Kumar Sharma and B. Ashish Solanki

ABSTRACT: In the modern era, the demand of construction is getting high, but land resources are getting exhausted and sometimes left behind option is to use soft soil, which requires ground improvement. Granular Piles (GP) are the most efficient and reasonable key for this problem. In this paper, a comparative study of a set of partly strengthened end-bearing GPs is presented, unfolding the comparison between analytical and rigorous analysis for several normalized aspects like displacement effecting component (DE) for top of GP, displacement interaction factor, percentage load shared by the base (PLSB) and values of normalized shear stress (NSS) across the length of the GP are assessed for end bearing set of two, three, four uniformly placed end bearing piles. The DE, for top of GP is noticed to get decline with the intensification in the values of the strengthening parameters. The interfacial shear stresses get reorganized along the length of the GP.
