Abstract

In the stabilization of embankment geo synthetic materials are widely used specificallygeogrids. Geogrids are laid horizontally to increase the stabilization of the slope. Geogrids are used to control the stability and settlement of embankment. Nowadays, soil enforcement of geogrids in conventional pattern is trustable and efficient way for increasing soil strength and stability. To increase the stability of embankment reinforcement are used, in stepped pattern. Usage of reinforcement is the less than the conventional pattern. In trapezoidal embankment the triangular area is weak to the load, so reinforcement is introduce. To achieve this embankment at a tank (70cmx40cmx50cm). It is used to analyze the effect of stepped geogrid under loading on Universal Testing Machine. The dimensions of the embankment is 25cm height, 20cm top length 50cm bottom length, width 40cm and slope failure of embankment with virgin soil at a distance of approximately dip 6cm to the slope. This failure plane was interrupted byproviding conventional and stepped pattern. It is aimed to compare the various pattern and percentage of reduction is material usage by introducing reinforcement at predetermined failure using Universal Testing Machine. It is observed that stepped pattern has reduction in material usage then conventional pattern.
