- A sequence of plate load tests (laboratory) were conducted to analyze the variations in load carrying capacity of geogrid-reinforced sand for different particle sizes (i.e –fine, medium and coarse sand). Geogrid sheets of circular shape and with diameter as 120 mm were provided in sand beds as reinforcement. All the sand beds were maintained at fixed relative density of 50%. The base plate (test plate) used as the surface foundation had a diameter of 60 mm. The effect of varying the number of geogrids and the varying the spacing between them on load-settlement characteristics was recorded and analyzed. The test results were used to interpret the improvement in load-settlement behaviour. The results showed that reinforcing sand beds with horizontal geogrid depicted improvement in the load carrying capacity of the sand beds. It was observed that by increasing the layers of geogrid, the load settlement behaviour improved further the bearing capacity improvement was observed by decreasing spacing between the geogrid layers.
