The differential settlement that occurs in a cap of impermeable soil over a landfill site is regulated by strict limitations from EPA requirements.  LCR&A conducted a study using three-dimensional, eight-noded finite elements.  A detailed investigation was made of the pattern of deformation, stress distribution, and the long-term settlement, with and without the proposed clay cap.
