STABLE USER MANUAL: A DESCRIPTION OF THE USE OF STABL'S PROGRAMMED SOLUTION FOR THE GENERAL SLOPE STABILITY PROBLEM

This report is a user manual for a computer program named STABL, developed to handle general slope stability problems by an adaptation of the Modified Bishop Method. The adaptation allows for analysis assuming shear surfaces of general shape. The value of the factor of safety obtained by this limiting equilibrium procedure, although not satisfying complete equilibrium, does compare favorably to more accurate methods, which use considerably more computing time and require evaluation of results for reasonableness. Critical surface searching options include three which genrate trail failure surfaces pseudo-randomly of circular shape, of sliding block character, and of general irregular shape. Data are read free-form and checked for compliance with program requirements. Errors are noted, if compliance is not satisfied. The profile and trial failure surfaces are plotted. Problem capabilities include; general profile definition; ground surface surcharge boundary loads; pore pressures approximately defined with respect to a free water surface, defined as a constant through a zone, related proportionally to the overburden, or defined as a combination of the aforementioned; anisotropic strength definition; and pseudo-static earthquake loadings.
