PROBABILISTIC ANALYSIS OF STABILITY OF EARTH SLOPES. PROCEEDINGS OF THE ELEVENTH INTERNATIONAL CONFERENCE ON SOIL MECHANICS AND FOUNDATION ENGINEERING, SAN FRANCISCO, 12-16 AUGUST 1985
A probabilistic method for the analysis of stability of slopes is presented. Determination of the probability of failure anywhere along the slope axis involves two steps. The first step concerns determination of the probability of occurrence of a potentially unstable zone, i.e., an area where the conventional factor of safety is less than unity. It is demonstrated that a real failure can only occur within such area. The second step involves evaluation of the probability that a real failure occurs, assuming the presence of a potentially unstable zone. In this step the effects of the finite width of a real failure mode must be taken into account. A procedure is suggested for updating the estimate of the probability of failure, if it is observed or may be assumed that certain states of loading actually have occurred and did not involve failure.
