Abstract: | Granular piles are becoming popular as technique of deep ground improvement not only in soft cohesive soils but also in loose cohesionless deposits. The present experimental study has been carried out on granular piles in sand (loose sand and dense sand i.e. R.D at 30% and 60%) with geogrid reinforcement. In this experimental investigation a group of five piles installed in sand, (at different spacing i.e s = 3d, 3.5d, 4d) the length and dia of the pile (L = 0.4 m and d= 50 mm) kept as same for all series of experiments. Geogrid reinforcement provided on granular piles , a limited number of laboratory tests have been conducted in laboratory to study the behavior of a granular pile , reinforced with geogrid layers, supporting a square footing ( at different s/d ratio's).The influence of geogrid layers providing on granular piles investigated through model tests. Geogrid reinforced granular piles has been found to result in significant increase in load carrying capacity and decrease in settlement reduction. Also the behavior of load carrying capacity and settlement with changing the s/d ratio has been carried out through a parametric study. |
