Reinforced Sandy Piles for Low-rise Buildings

At present a number of techniques for artificial strengthening weak foundation soils have been developed and implemented, most of them having poor efficiency due to expensive materials and equipment used. Therefore, studying and developing new ways to improve soil bearing capacity is an urgent task. The paper presents the experimental study of one of the ways to improve soil bearing capacity and stability through introduction of a sandy pile reinforced vertically along the contour with a geosynthetic permeable element (geogrid CCP 30/30 – 2.5). A technique for determining the temporal strain condition of the given structure has been developed after the linear theory of viscoelasticity. Theoretical calculations for the vertical movements of the pile body, comparable with the results of in-situ tests are presented.
