... with geogrid at the interface. Three pairs of model footings of different sizes are used in the study. The width (B) and length (L) of the footings are chosen in such a way that the L/B ratio (aspect ratio) of the footings is varied as 1.0 (square), 1.5 (rectangular) and 2.0...

...S. Saha Roy; K. Deb Model plate load tests of rigid rectangular footings of different aspect ratios resting on sand overlying soft soil with or without a layer of geogrid at the interface are presented. The width (B) and length (L) of the footings are chosen so that the L...

...-reinforced and rigid-facing retaining walls need to be identified. In the present study, a series of centrifuge model tests on retaining walls reinforced by geocells were performed. The tests varied with respect to aspect ratio (the reinforcement length to the height of the wall) and the slope inclination...

... of polypropylene fibre reinforced sand specimens considering different fibre lengths (up to 50 mm) and diameters (from 0.023 mm to 0.1 mm fibre), resulting in a large spectrum of aspect ratios (up to approximately 2200). Fibre reinforced specimens exhibited either strain-softening or strain-hardening...

...N. M. Al-Akhras; M. F. Attom; K. M. Al-Akhras; A. I. H. Malkawi This study investigated the effect of two types of fibers (natural and synthetic) on the swelling properties of clayey soils. Nylon and palmyra fibers with different aspect ratios (L/d) were mixed with three types...
