Analysis of railway embankment under varying sub soil conditions for different height of embankments

The paper discusses the analysis of a railway embankment of different height varying from 4m to 20m for different types of natural soils. Five embankments of different height (4m,8m,12m,16m and 20m) are modeled as per RDSO guidelines and analysis is performed for four diifrent types of soils in natural ground while the property of soil used for the formation of embankment is same in all the cases The effect increase of height of embankment on the stability of slopes is studied. Also the effect of soil type on the stability of slopes is studied.in all the cases water table is assumed to be 10 m below the ground surface. it is found that increase in the height of embankment result in a decrease of factor of stability. Also the factor of safety is very low for soft clay. for cases where f.o.s is less than 1.4 provision of retaining are analysed after provision of retaining wall and also with an increment of their slopes.
