Abstract
Geo synthetics are commonly used for reinforcement of embankments and retaining structures. They score over the traditional methods in terms of effectiveness, cost and speed of construction. The mechanism of geogrid reinforced embankment is to provide a stable force at the soil-geogrid as a result of the interlock and friction action between the layer particles and grid, and to provide membrane reinforcement. Several studies have been conducted to analyze the performance to geogrid reinforced embankment supporting road or rail infrastructure but the interface interaction between the geogrid with embankment soil and between the pavement and the embankment fill is not considered comprehensively in the existing literature. The time dependence of geogrid reinforcement properties is also not considered. Further optimum geogrid spacing of geogrid as a function of embankment height and slope also, needs to be examined. The aim of this study the impact of these factors on the stability and performance on the embankment using numerical analysis tools. The results of the study are graphically represented in form of total and differential settlements, displacement and stress contours and strain developed in the geogrid reinforcement.
