Experimental and numerical study of compression and tension test on pile

Abstract

In this study, eighteen tests on mild steel piles, rough piles & smooth piles embedded in a cohesionless soil were carried out in the laboratory to assess the effect of compression and tension capacity of piles & group of piles considering various parameters. The model piles were of 50mm outside diameter, 2mm wall thickness and 600mm length whereas smooth and rough piles dimensions were 40,50,60mm in diameter and 600mm length. Subsequently, group of piles of 10mm dia of different length and spacing values were carried out for compression test and tension test was carried out only on single pile. The pile was embedded in sand for embedment length/diameter ratios of 500mm inside a model tank. They were subjected to a static compressive and tensile load with respect to settlement values which was measured through displacement dial gauges & proving ring arrangement. A logical approach based on the experimental results, will give suggestion to predict the future site testing results by enlarging the dimensions of piles, increasing the loading values and various parameters respectively.
