Abstract

In this study, the experimental investigation of model footing on crusher dust as an alternate granular soil with geotextile and geogrid as reinforcement is discussed. The experimental investigations were made separately with geotextile and geogrid with one to three layers in model tests at different relative densities. The bearing capacity was obtained from the load-settlement curve using the double-tangent method. The experimental results were validated through finite element analysis using commercial software Plaxis 3D. The friction between reinforcement and crusher dust is more than compared to that of natural sand, which may be due to surface roughness of crusher dust. The variations in bearing capacity of footing on geotextile and geogrid at different relative densities are compared in terms of bearing capacity factor Nγ. A parametric study was also presented in terms of variations of bearing capacity ratio of model and real-scale footing.
