Base resistance of individual piles in pile group

The base resistance of individual smooth model piles in the pile groups in sand under static loading is investigated experimentally in a pile soil test apparatus. The aim of the laboratory tests was to study and evaluate the behaviour of individual smooth model piles in the 5 and 9-pile groups under axial load with two different pile spacing in two different soil densities [medium dense and compacted] around the piles. The study show the effect of soil improvement around the piles in increasing the base resistance of individual smooth model piles in pile groups. The laboratory tests outlines the variation of the magnitude and the proportion of end bearing capacity of individual piles in different pile groups.
