Abstract

A numerical study of the behavior of an inclined loaded strip footing resting on geogrid-reinforced sand is presented. The effects of number of geogrid layers, relative density, load inclination and failure mechanism were considered in the finite element (FE) analysis, assuming plane strain conditions. Test results indicate that the footing performance could be appreciably improved by the inclusion of layers of geogrid leading to an economic design of the footing. However, the efficiency of the sand-geogrid system depends on the load inclination and reinforcement parameters. A close agreement between the experimental and numerical results is observed. Based on the numerical and experimental results, critical values of the geogrid parameters for maximum reinforcing effect are established.
