## ANALYTICAL PROCEDURE FOR SLOPE STABILITY CALCULATION USING RIGID-PLASTIC MODEL

The problem of slope stability of natural and artificial embankments is explained. A brief review of popular methods of slope stability calculation (in terms of embankments and excavations) is given with their key advantages and shortcomings. A feature of each method is the number of included equations of equilibrium. This article proposes a procedure for solving the problem on slope stability using a rigid-plastic model to describe the processes of instability and shearing. The procedure provides solution of a system composed of two or three equations derived by the author of this article. Alongside with the slope geometry and physical and mechanical properties of soil, a function of instability is set, and the solution is found in the form of this function. The algorithm of the problem solution using the proposed procedure is described. The feature of this procedure is the problem solution in the form of an analytically preset rather than piecewise-linear function. The procedure implementation is illustrated in terms of a vertical slope.
