For the slope stability study conducted during the second year of the project, an experimental papermill sludge landfill was altered by removal of the north dike. Next the landfill was excavated to form a 3:4 slope and two weeks later was trimmed to a 1:8 slope. It was shown that soil mechanics theory can be used to predict the stability of slopes excavated in a sludge landfill. Development of failure zones for the 1:8 slope was studied using the finite element method of analysis and laboratory triaxial test data. Stability analysis of the 1:8 slope, using Janbu's method for a composite failure surface, gave excellent agreement between the actual factor of safety and the computed factor of safety. Additional information on physical properties of the sludge shows the dependence of liquid and plastic limits on the organic content of the sludge. The low permeability of the high ash papermill sludge together with a decreasing rate of leachate flow associated with fill consolidation exerted a moderating effect on the quantity of leachate leaving the landfill.
