摘要：

The art of soil reinforcement has so far been restricted to the problem of 'strengthening' cohesionless materials. The present work is aimed at exploring the feasibility of using tensile geogrids for the purpose of controlling the swell of plastic soils. Swelling tests using an enlarged oedometer revealed promising results. The reinforcements were cylindrical geogrids of varying stiffness values embedded in clays of different plasticity indices. The reduction in swell increased with increasing the geogrid stiffness, apparently due to a strong 'interference' bond restricting the relative movement between clay and the grid. A footings model test confirmed the effectiveness of the proposed technique.
