Embankments and manmade excavations are frequently used engineering structures to facilitate construction of earth dams, roads, railways, river training works, mining excavations, landscape engineering and landfills. Retaining the man-made slope is always a problem in geotechnical engineering and solution to this problem keeps evolving with advancement in technology. The study of slope stability is considered to be very important, because this helps in avoiding damages to structures and saving in cost as well, also this supports the understanding of slope failure mechanism and exploring ground improvement techniques. Methods used for slope stabilization are flattening of the slopes, constructing of earth retaining structures and ground improvement methods like foundation grouting, inserting micro piles, reinforcement with geosynthetics products, mechanical and chemical stabilization. The present study discusses about the slope stability problem of switchyard area in one of the hydroelectric project. The issues faced during design of embankment for switchyard are (i) Embankment base is on weathered poor quality rock, (ii) heavy load from switchyard machinery and (iii) limited space. To address these issues, analysis with bi-axial geogrid as soil reinforcement is adopted to design the slope, by analyzing for all the expected loading conditions and meeting minimum factor of safety criteria. The results of comparative stability analysis carried out using slope stability SLIDE software, for six different loading conditions, without soil reinforcement and with soil reinforcement, are presented in this paper.
