Bearing Capacity Improvement of Sand Bed Reinforced with 3D Geogrids of Rectangular Pattern
Abstract In this paper, the effect of three-dimensional geogrid as a reinforcing material in enhancing the bearing capacity and settlement behaviour of reinforced soil is investigated. Laboratory-scaled plate load tests have been conducted to study the performance of square footing resting on the sand bed reinforced with 3D geogrids of rectangular pattern. The results show that a single layer of 3D geogrid placed at a depth of 0.25B from the bottom of footing provides a threefold increase in bearing capacity compared to unreinforced soil. The optimum spacing between two consecutive layers of 3D geogrids was obtained as 0.75B. Soil reinforced with two layers of 3D geogrid gives higher bearing capacity improvement (6 times) and a further increase in the number of layers does not show any significant improvement in bearing capacity. The results obtained from this study shows that 3D geogrids can be used as an effective reinforcing material in improving the mechanical properties of reinforced soil structures such as embankments, retaining walls, shallow foundations, stabilization of steep slopes, etc.
