Annotation: A probabilistic method of determining slope stability ratio allowing to estimate and compensate the drawback caused by the spread in particular values is described. The stability situation of an arbitrary slip surface slope in order to use the results for the different stability calculation methods is considered. It is proved that the inhomogenuity of ground layer structure and the inequality of slip curve distribution of restraining and shearing forces must be taken into account to improve the accuracy of determining slope stability ratio. Inherently given approach reflects the method of determining the normative and soil characteristics. Based on the investigation results a universal algorithm for determining design values of the slope stability ratio using the mathematical statistics methods has been developed. It is pointed out, that the main advantage of the proposed method of determining stability ratio compared to the generally accepted methods is in the ability to determine the range of change at a given confidence coefficient interval.
Keywords: slope, stability ratio, probabilistic method, shearing and restraining forces, design and normative characteristics, ground safety factor.
