Stability Enhancement of Railway Embankment Using Geosynthetic Layer
Across the world, day by day there has been an increase in demand for geotechnical structures which are more economical and environmentally acceptable. Cohesive soils being one of the most abundant and cheapest construction materials, their use can be extended by improving its engineering performance by incorporation of reinforcing elements such as geogrid. The present study summarizes the strength enhancement of railway embankment based on the factor of safety which is calculated by Bishop method through GeoStudio software by incorporating geogrid in embankment layer which is of cohesive soil. The main objective of this study is to indicate the correlation between the factor of safety of embankment with or without incorporating geogrid in it. These are the parameters which have been used as input parameters in this test as cohesion value (c), angle of shearing resistance (φ), unit weight (γ) for both subsoil and embankment layer, respectively, and pull-out resistance (PR), tensile capacity (TC) for geogrid. After varying its properties, it has been observed that there is a continuous increase in the factor of safety after incorporating geogrid in the embankment layer. Based on the experimental result, it has been found that the railway embankment stability has been enhanced by incorporating geogrid in the embankment layer.
