The progressive consumption of coal
generates bulk quantities of coal ashes which is disposed
in the form of slurry in ash pond. The limitations of
available lands may further results in the construction of
pond ash dyke raising for higher storage. The stability of
ash dyke raising has been a major concern over a year
for a geotechnical engineer. In the present investigation,
stability of pond ash dyke has been analyzed under
different numbers of raising by Bishop’s Method.Factor
of safety value of ash dyke under static and seismic
conditions have been determined using GEOSLOPE
Software. The outcome of present investigation
suggested an optimum number of raisings under static
conditions and seismic
