Non-probabilistic Reliability Analysis Based on the Ellipsoidal Model of Rock Slope Stability

For evaluating the slopes' stability accurately and quickly, non-probabilistic reliability based on the ellipsoidal model is used to overcome the existing disadvantages.Firstly, uncertain parameters are considered via the ellipsoidal model of the rock slope.And then the corresponding methods are used to calculate the non-probabilistic reliability index to evaluate the slope's stability.Finally, the Monte-Carlo simulation were carried out to evaluate the rock slope's stability as a comparison.The result shows that the non-probabilistic reliability analysis is more efficient and applicable.
