ULTIMATE BEARING CAPACITY OF ECCENTRICALLY LOADED STRIP FOUNDATION ON GEOGRID-REINFORCED SAND

Laboratory model test results for the ultimate bearing capacity of eccentrically loaded strip foundation supported by sand reinforced by layers of geogrid have been reported. The model tests were conducted at 70% relative density of compaction of sand. The load eccentricity ratio was varied. From the model test results, the critical depth of location of the first layer of geogrid and the extent of the geogrid reinforcement measured from the bottom of the foundation for mobilization of maximum bearing capacity have been presented. Test results have also been presented for determination of the optimum width of the reinforcement layers.
