Abstract

The paper discusses the analysis of a road embankment of different heights for sandy soil under different variations of embankment slope. Four embankments of different height (1.5m, 3m, 5m and 6m) under four variations of slope (1H:1V, 1.5H:1V, 2H:1V and 2.5H:1V) were modelled in Geostudio2018 and the analysis is performed for the stability of slope of road embankment for different values of unit weight and friction angle of sandy soils by Bishop’s method of slope stability using Geostudio2018 software. The effect of increase of height of embankment on the stability of slopes is studied. Also the variation of soil property on the stability of slopes is studied and it is found that increase in the height of embankment result in a decrease of factor of safety against slope failure. For cases where factor of safety is less than 1.4, they are considered to be the case of slope failure as per the guidelines of IRC75:2015.
