the bearing capacity of a square footing ðq s Þ
at the same settlement on unreinforced pond ash, settlement to width of the footing ratio ðs=BÞ
in percentage, number of layers (N) of reinforcement, friction ratio (f), i.e. the ratio of the
pond ash—geotextile interface friction angle (c) to the direct shear friction angle of pond ash
ðf d Þ; depth of the upper most layer of reinforcement from the base of the footing to width of
the footing ratio ðu=BÞ; length of reinforcement sheet to width of footing ratio ðL s =BÞ and
vertical spacing of the reinforcement to width of the footing ratio ðS v =BÞ are found to be
significant to the model
