... ABSTRACT Angouran zinc-lead open pit mine, located in the northwest of Iran, has experienced a large-scale slope failure in the order of 12Mm 3 volume. The main challenges due to this giant failure are subsequent responses of the sliding mass, geometry of the slip surface, and where unloading...

... probability of complicated slopes. A new adaptive ant colony algorithm (AACA) is proposed to determine critical slip surface and its corresponding failure probability of complicated slopes. A case study is given to verify the proposed approach. The results show that the presented method has obvious advantages...

...) grid-based 3D deterministic model and taken the slope unit as the study object, the landslide hazard is mapped by the index of the 3D safety factor. Assuming the initial slip as the lower part of an ellipsoid, the 3D critical slip surface in the 3D slope stability analysis is obtained by means...
