Non-Probabilistic Slope Stability Analysis
A high filled subgrade of a highway slipped on the left of the line. According to conventional calculations (limit equilibrium method) ,we can know that the safety factor K = 1.55 and the probability of reliability index β = 3.1, failure probability Pf = 0.001. Through the introduction of interval analysis theory, non-probabilistic reliability calculation model is established, and the non-probabilistic reliability index is η = 0.7. Showing that the non-probabilistic reliability theory in the absence of adequate data distribution of information and possible subjective assumptions can also obtain more accurate results.
