Large-Scale Experiment on Shallow Cover for Buried Pipeline Reinforced with Geosynthetics
A series of tests for buried pipelines were performed to investigate the effectiveness of geogrids in enhancing the float up resistance of buried pipes due to buoyancy. The experiments were conducted using 1100-mm diameter pipes in a model sand ground. In the experiments four types of pipe floatation prevention methods were installed around a buried pipe with a shallow depth of cover. The prevention method consisting of a geogrid and gravel backfill material employed to increase the float up resistance of buried pipes. For shallow depths of soil cover the incorporation of geogrid reinforcement can lead to a decrease in cover to extremely shallow depth. The geogrid reinforced tests show that the forces preventing pipe floatation are contributed to by the dead weight of the overlying soil as well as bending mode deformation of the reinforced layers surrounding the pipe.
