The purpose of the research was to develop a computer-assisted system of stability analysis for specific reservoir slopes. The versatility of the developed programs includes accommodations for variable ground surface and profile characteristics, both uniform and concentrated external boundary loadings, spatial variations in water pressure, and irregular as well as circular shaped failure surfaces. Several limiting equilibrium analyses by methods of slices have been reviewed. One of these, the modified Bishop technique, previously considered applicable only to circular failure surfaces, was modified to include irregular shaped surfaces. The programs have been written in elementary Fortran IV language. There are currently five main programs and eleven integrated supporting routines. Conversion of the programs to small computer systems is considered highly practical.
