Study on the Deformation and Mechanical Properties of Geogrid-Reinforced Sandbag Revetments
To advance the understanding of the deformation mechanics in geogrid-reinforced sandbag embankments,a series of model tests were conducted,comparing embankments without geogrid reinforcement(NGR)and those with geogrid wrapping reinforcement(GWR).The strain variations in the geosynthetics within the embankments were analyzed.Based on the experimental data,theoretical strain equations for both the geogrid and sandbags were established.A deformation mechanics model was subsequently developed for GWR-reinforced embankments,from which functional relationships between embankment settlement,geogrid strain and stress,and sandbag strain and stress were derived.The results indicate that GWR significantly reduces the stress levels in sandbags,with the geogrid experiencing considerably higher stress than the gauze,effectively bearing the majority of the embankment's load.The proposed deformation mechanics model was validated through experimental tests,demonstrating a high degree of accuracy.The application of this model enables real-time monitoring of embankment reinforcement projects,contributing to more precise and scientifically informed safety management of embankment structures.
