Effect of Compaction on Deformation Pattern of Soil Reinforced with Vertical Piles under a Vertically Loaded Foundation

Abstract

The paper presents results of field load-settlement tests of full-scale foundations, resting on granular sub-soil base of different densities, and reinforced with concrete piles. The study was carried out in a construction site in Minsk, Belarus. Deformation patterns of the sub-soil bases under vertically loaded foundations were studied. The results of the study show similar variation in the patterns of vertical deformation of the sub-soil bases at both loose and dense state. But patterns of the deformation of the soils along horizontal axis shows loose sub-soil base, having maximum deformation along the center line of the foundation plate, while for dense sub-soil base, the deformation takes the pattern for rigid footing on a cohesive base, with maximum deformation recorded along the edges of the foundation plate.
