Influence of Footing Size on Reinforcement Geometrical Parameters
The load-bearing capacity of the reinforced sand bed depends on the optimum geometrical parameters of the reinforcement layer. This paper presents the effect of the size of the footing (D) on optimum geometrical parameters of the reinforcement, that is, placement depth of the first reinforcement layer (u) and the vertical spacing between the reinforcement layers (h). The jute geotextile reinforcement layer was used for the present model tests. All model tests were conducted using 50 mm diameter circular footing in a steel tank having an inner dimension of 450 mm × 450 mm × 350 mm. In each test, sand was placed at a relative density (Rd) of 70%. Finally, the present test results are compared with the plate load tests of jute geotextile reinforced sand beds using footing diameter (D) 150 mm. The size variation factor for two different diameters (D) of footings is 3. The test results show that the values of optimum geometrical parameters of the reinforcement are not much varying with the respective size of the footing (D). In comparison, the variation with the respective size of the footing is relatively higher for optimum vertical spacing of the reinforcement (h) than the optimum placement depth of the first reinforcement layer (u).
