Abstract
The paper presents a slope stability analysis of a proposed embankment contained within an abandoned coal mine reclamation project near Sallisaw, Oklahoma. The project involved the use of computer modeling to analyze the slope stability of the earth-filled embankment. The project plans call for mine spoils and silty-clay borrow materials is used to construct a 74,000 cubic yard embankment, which will be used as a water impoundment for a small lake. The embankment, as designed, consists of a central clay core, mine spoils and a silty-clay material cap. The software program Galena was used as a modeling tool for the slope stability analysis of the proposed embankment. Additionally, seven different variations on the embankment’s proposed design were modeled. The ultimate goal was to determine the factor of safety (FS) for each variation. Results show that the Galena program provides a higher factor of safety when compared with conventional methods using the Taylor stability chart. The difference in these values is probably attributed to the general assumptions of the Taylor method.
