r I APPENDIX C SLOPE STABILITY ANALYSES The site slope was analyzed for stability along Cross Sections A -A', B-B', and C-C' using the computer program WinStabl, by the University of Wisconsin. WinStabl is a two-dimensional, limit equilibrium slope stability program that generates random potential failure surfaces and determines their corresponding lactors of safety with respect to failure. By generating a large number of random surfaces, a pot lial failure surface with the minimum factor of safety can be obtained We perfornied stability analyses using inforniation gathered from our field explorations and laboratory analysis and have assigned soil properties to the soil layers to reasonably reflect their engineering characteristics. The results of the analyses are presented as Figures C-1 through C-12. A description of the results can be found in the body of the report. NELSON GEOTECHNICAL ASSOCIATES, INC. 57
