UPLIFT BEHAVIOR OF PLATE ANCHORS WITH GEOSYNTHETICS

The uplift behaviour of plate anchors embedded in cohesive and cohesio nless soil media, with and without geosynthetics, has been investigate d with the help of small-scale model tests in the laboratory. Many fac tors, such as the type of geosynthetics, the ratio of the area of the geosynthetic inclusion to the area of the plate anchor, the depth of e mbedment, the type of soil, the strain rate and the position of the wa ter table, have been found to significantly influence the uplift behav iour of plate anchors. In most of the reinforced earth techniques, coh esionless fill is more or less indispensable. However, it is observed from the present investigation that both cohesionless and cohesive soi ls can be employed to enhance the uplift capacity of plate anchors and footings, with geosynthetic inclusions.
