The results of a study to select methods for analyzing the stability of crater slopes are presented in this report. Information is given on the nature of input required, such as crater geometry, unit weights, shear strength, and seepage pressures. The selected methods are discussed in detail, and examples of their application are presented. The report does not describe all methods which are found in literature, although these were reviewed during the study. The three selected methods presented are a the Bishop method of slices for circular slip surfaces b the extension of Bishops method to composite failure surfaces as proposed by Janbu and Nonveiller, and c the Seed and Sultan method of wedges. These methods were selected as representative of the best available limiting equilibrium procedures. Author
