A compacted fill slope is to be made of a soil with a c' = 200 lb/ft?, p'= 30° and y= 122 Ib/ft. Using an infinite slope analysis and assuming a failure surface 4.0 ft vertically below the ground surface and a groundwater table 1.3 ft below the ground surface, determine the steepest allowable slope ratio that will maintain a factor of safety at least 1.5. This analysis considers only surficial stability and a separate analysis would need to be conducted to evaluate the potential for a deep-seated slide in the fill. Hint: This may involve iteration using a spreadsheet or a similar approach.
