INFLUENCE OF GEOSYNTHETIC REINFORCEMENT ON GRANULAR SOILS

Model test results of strip footings on geosynthetic reinforced granular soil deposits are presented. The deposits consisted of a thin strong layer of granular material placed on a weaker granular material and a uniform single layer of the same weak granular material. The two-layer soil deposit was reinforced with a single layer of geosynthetic reinforcement. The uniform soil deposit was reinforced with one or two layers of geosynthetic reinforcement. The buried depth of the geosynthetic reinforcements was varied to determine the optimum position of placement. The optimum was based on maximizing the ultimate bearing capacity of the footing and reducing its settlement. The effect of repeated loading on the behavior of the geosynthetic reinforced granular deposits is also examined. The best method for improving the performance of weak granular soil deposits is concluded from the results.
