Geotechnical analysis is usually used to determine the essential properties of a soil whose behavior is affected under known field-loading condition. The present study was conducted to determine the feasibility of dry stacking of bauxite waste with minimal adverse effect on the integrity of the disposal facility. Red mud samples obtained from a disposal facility were analyzed for their geotechnical properties. Tests conducted include confined consolidation, vane shear, Atterberg limits, specific gravity, moisture content and pH. Data from these tests were used to predict the stability of different heights and slopes for stacking the red mud in the storage facility.;Laboratory testing showed the specific gravity of samples ranged from 2.72–3.70, plastic limit from 18–49, liquid limit from 47–94, shear strength value from 0 Kpa–9 Kpa, pH from 10.30–12.20, moisture content from 31.2%–228.8%, and void ratio from 1.00–2.37 for loading pressure of 5 Kpa and 0.05–2.01 for loading pressure of 80 Kpa.;Slope stability analysis using REAME software showed that the disposal facility is stable under present loading condition, but when the red mud is stacked at the peak elevation of 70 feet, the structure would not be stable.
